Hazard Mitigation Plan
1.0 Introduction
This Hazard Mitigation Plan is a guide for Pottawatomie County citizens to prepare for possible natural
disaster events by taking action to help mitigate the effects of potential hazards. The plan was prepared for
Pottawatomie County and participating local jurisdictions through the efforts of the Mitigation Planning
Committee (MPC) in conjunction with E-Fm Consulting, LLC. As part of an overall multi-jurisdictional
planning effort, this plan has been created by the participating entities to comply with the Disaster
Mitigation Act of 2000 (Public Law 106-390, hereinafter referred to as DMA 2000).
Section 1.0 provides a general introduction to the Pottawatomie County Multi-Jurisdictional Hazard
Mitigation Plan. It is organized into the following five sections:
1.1. Background 1.2. Purpose 1.3. Scope 1.4. Authority 1.5 Paper Reduction and Elimination
1.1 Background
Natural phenomena such as floods, tornadoes, and severe storms, are a part of the world around us. As
part of nature, their occurrence is inevitable; there is little we can do to control their force and intensity.
However, through hazard mitigation planning, we can minimize the impact these events have on our lives
and property.
Hazard mitigation is simply a technical term for reducing risk to people and property from natural
hazards. It includes structural measures, such as protecting buildings and infrastructure from the forces of
wind and water, as well as non-structural measures, such as natural resource protection and wise
floodplain management. These activities can help protect both existing development and, by mitigating
potential hazards to new construction, future development. It is widely accepted that the most effective
mitigation measures are implemented at the local government level, where decisions on the regulation and
control of development are ultimately made.
The easiest and best way a jurisdiction can develop serious intentions about hazard mitigation is through
the development and adoption of a local hazard mitigation plan. A mitigation plan will ensure that
measures to reduce the present and future vulnerability of a jurisdiction are thoroughly considered before,
during, and after a disaster strikes.
Mitigation planning in compliance with the requirements of DMA 2000 offers many benefits.
These include:
•
•
•
•
•
saving lives and property;
saving money;
speeding recovery following disasters;
reducing future vulnerability through wise development / redevelopment;
expediting both pre-disaster and post-disaster grant funding by demonstrating a firm commitment to
improving jurisdiction health and safety.
Recently, both the State of Kansas and the U.S. Congress made the development of a hazard mitigation
plan a specific eligibility requirement for any local jurisdiction applying for mitigation grant funding.
Jurisdictions with an adopted plan will therefore become pre-positioned and more apt to receive any
available mitigation funds.
More importantly, mitigation planning has the potential to produce long-term and recurring benefits by
breaking the repetitive cycle of disaster loss. A core assumption of mitigation is that current dollars
invested in mitigation practices will significantly reduce the demand for future dollars by lessening the
amount needed for emergency recovery, repair and reconstruction in the event of a disaster. These

mitigating practices will assist residents, their businesses and local industries to recover faster in the wake
of a disaster, enabling the jurisdiction's economy to re-establish itself sooner and with less interruption.
Mitigation planning will also lead to benefits beyond the main purpose of hazard vulnerability reduction.
Measures such as the acquisition or regulation of land in known hazard areas can help achieve
jurisdictional goals such as preserving open space, maintaining environmental health and natural features,
and enhancing recreational opportunities.
1.2 Purpose
As mentioned above, this plan was created in an effort to help Pottawatomie County and participating
local jurisdictions to come into compliance with the requirements of DMA 2000. The purpose of this
Hazard Mitigation Plan is:
• To protect against the loss of life in the event of a disaster;
• To preserve the safety of persons and property by reducing the risk of potential damage and economic
loss in the event of a disaster;
• To qualify for additional grant funding, both pre- and post-disaster;
• To qualify for participation in the National Flood Insurance Program (NFIP), and the Community
Rating System (CRS) to receive additional credits under the program;
• To speed recovery and redevelopment following future disaster events;
• To demonstrate a firm local commitment to hazard mitigation principles;
• To comply with both state and federal legislative requirements for local hazard mitigation plans.
1.3 Scope
This Multi-Jurisdictional Mitigation Plan was developed under a Federal Emergency Management
Agency (FEMA) hazard-planning grant awarded to Pottawatomie County through the Kansas Division of
Emergency Management. Pottawatomie County approved E-Fm Consulting, LLC's contract on June 2,
2008.
The plan identifies the natural and state-mandated hazards associated with the county, but is developed
primarily to address hazards classified as high and moderate in the probability and vulnerability (severity)
analysis model. Hazards classified in the low or negligible categories were eliminated because of their low
rating priority or because of inadequate county infrastructure or fiscal capabilities. The MPC may add
specific hazards to the prioritized hazards list to confirm local jurisdiction planning needs are met.
Hazards will be reviewed on a routine basis with plan updates as circumstances change.
The geographic scope for the Hazard Mitigation Plan includes both the incorporated and unincorporated
areas of Pottawatomie County, as provided in Section 2.0 of this plan.
1.4 Authority
Local governments in Kansas have a wide range of tools available to them for implementing mitigation
programs, policies, and actions. In implementing a mitigation plan or specific action, a local jurisdiction
may utilize any or all of the four broad types of government authority granted by the State of Kansas.
Those four types of authority are defined as: (a) regulation, (b) acquisition, (c) taxation, and (d) spending.
The scope of this local authority is subject to constraints, however, as all of Kansas political subdivisions
must not act without proper delegation from the State. Under a principle known as Dillon’s Rule, all
power is vested in the State and can only be exercised by local governments to the extent it is delegated.
Kansas local governments have been granted broad regulatory authority in their jurisdictions. Kansas
General Statutes (K.A.R.) bestow the general police power on local governments, allowing them to enact
and enforce ordinances which define, prohibit, regulate or abate acts, omissions, or conditions detrimental
Page 6 of 252
to the health, safety, and welfare of the people, and to define and abate nuisances (including public health
nuisances).
Since hazard mitigation can be included under the police power (as protection of public health, safety, and
welfare), towns, cities, and counties may include requirements for hazard mitigation in local ordinances.
Local governments may also use their ordinance-making power to abate nuisances, which could include,
by local definition, any activity or condition making people or property more vulnerable to any hazard.
After approval of the Multi-Jurisdictional Plan by the State of Kansas and FEMA (ref. Sec. 2.2), the plan
can then be implemented by the County Board of Commissioners and the Executive Officers of the local
jurisdictions under the authority of and by the police powers bestowed on them by the State of Kansas.
This Plan has been developed to be in accordance with current rules and regulations governing local
hazard mitigation plans. The Plan shall be routinely monitored to maintain compliance with the following
legislation:
1. Home Rule Powers: Article 12 Section 5 – Kansas Constitution 2. Kansas Emergency Planning
and Jurisdiction Right-to-Know Act, K.S.A. 65-5701 through 65-5711, and Superfund Amendments
and Reauthorization Act of 1986 (SARA), Title III, Emergency Planning and Jurisdiction
Right-to-Know Act (EPCRA), Pub. L. 99-499 (a) Federal Civil Defense Act of 1950, Pub. L. No.
81-920, as amended (b) K.A.R. 56-2, Standards for Local Disaster Agencies 3. The Robert T.
Stafford Disaster Relief and Emergency Assistance Act as amended by the Disaster Mitigation Act
of 2000 (Public Law 106-390 – October 30, 2000).
1.5 Paper Reduction and Elimination
It is the goal of this planning process to comply with the overall direction to reduce or eliminate the use of
paper. The 1998 Government Paper Elimination Act (GPEA), and consequent clarification by the Office
of Management and Budget, asks all entities to consider eliminating paper as the vehicle to provide
information or data to and from the Federal government. This mitigation plan is intended to be read,
maintained, and edited in its online version.
As an interim step towards this goal, the plan can be printed using the standardized portable document
format (PDF). When printed in this format, the formatting that is seen on-the-screen has been reduced and
partially compacted in order to save paper when ultimately printed. Consequently, text may not carry with
the associated table or image to the next page. The full content will be included in the PDF file. Thank
you for your consideration of the Planning Committee's goal.

2.0 Planning Process
• Multihazard Requirement §201.6(a)(3): Multi-jurisdictional plans (e.g., watershed plans) may be accepted, as
appropriate, as long as each jurisdiction has participated in the process … Statewide plans will not be accepted
as multi-jurisdictional plans.
Hazard Mitigation is defined as any sustained action taken to reduce or eliminate long-term risk to human
life and property from hazards. Planning is the process of setting goals, developing strategies, and
outlining tasks and schedules to accomplish those goals.
Hazard mitigation planning is the process through which natural hazards that threaten jurisdictions are
identified, the probability and severity of those hazards are determined and prioritized, mitigation goals
are set, and appropriate strategies are created to meet those goals.
Hazard mitigation planning is required for state and local governments to maintain their eligibility for
certain federal disaster assistance and hazard mitigation funding programs. Jurisdictions at risk from
natural disasters can ill afford to jeopardize this funding.
Each year, natural disasters in the United States kill hundreds of people, injure thousands more and
destroy private and public property and infrastructure. Nationwide, taxpayers pay billions of dollars
annually to help jurisdictions, organizations, businesses and individuals recover from disasters. These
monies only partially reflect the true cost of disasters, because additional expenses to insurance companies
and non-government organizations are not reimbursed by tax dollars.
Additionally, many natural disasters are predictable. Many more are repetitive, often with the same
results. Many of the damages caused by these events can be alleviated or even eliminated.
FEMA, the Federal Emergency Management Agency, now a part of the Department of Homeland
Security, has targeted reducing losses from natural disasters as one of its primary goals. Hazard mitigation
planning and subsequent implementation of projects, measures, and policies developed through those
plans, is the primary mechanism for achieving these goals. As a result of successful mitigation planning,
when mitigation projects have been implemented, damages have been reduced. More importantly,
proactive mitigation planning at the local level can help reduce the cost of disaster response and recovery
to property owners and government by protecting critical facilities, reducing liability exposure, and
minimizing overall jurisdiction impacts and disruption.
2.1 Participants
Multihazard Requirement §201.6(c)(1): [The plan shall document] the planning process used to develop the
plan, including how it was prepared, who was involved in the process, and how the public was involved.
The Mitigation Planning Committee (MPC) represents participating local governments, including
incorporated cities, towns, schools and other qualified government entities (referred to as
sub-jurisdictions) of Pottawatomie County. The MPC seeks a coordinated and active mitigation planning
process with full participation in plan development and implementation. This integrated planning process
combines the risks, issues, goals, and mitigation measures of each jurisdiction to form a
Multi-Jurisdictional Mitigation Plan.
Representatives from participating jurisdictions attended committee meetings and completed planning
activities during the drafting stage of the plan. The minimum level of committee participation for each
jurisdiction was achieved by one or more representative that were actively involved in the planning
activities conducted during the drafting phase of the plan. Persons authorized as representatives to serve
on the committee for any given jurisdiction are provided in Table 2.1 (1).
The development of this Multi-Jurisdictional Mitigation plan, which was completed in March 2010,
included input and comment from individuals, local and state public agencies, private groups, business
operators and owners. The Pottawatomie County Mitigation Planning Committee itself was made up of

Participating Jurisdictions
The following jurisdictions were invited to participate in the Pottawatomie County planning process. Plan
participation was accomplished by jurisdictional representation in one of three ways: (1) direct
representation by a person from the jurisdiction, or (2) delegation of jurisdictional representation to a
qualified third party, or (3) delegation of jurisdictional representation to a consultant contracted for this
project. Pottawatomie County jurisdictions chose the third form of representation which appoints the
consultant as Plan Author and, where jurisdictions lack the resources or personnel to attend all planning
meetings, delegates the authority to the consultant to represent them. Resolutions authorizing the Hazard
Mitigation Plan consultant to represent them and to prepare the plan on their behalf are included in the
Page 11 of 252
Appendix. Jurisdictions that have promulgated authorization for representation have met the minimum
criteria for participation as set forth under the Requirements section and are therefore considered by the
Pottawatomie County Planning Committee as eligible participating jurisdictions.

2.2 Plan Adoption
Multihazard Requirement §201.6(c)(5): For multi-jurisdictional plans, each jurisdiction requesting approval of
the plan must document that it has been formally adopted.
The Pottawatomie County plan was developed as a multi-jurisdictional plan. Therefore, to meet the
requirements of Section 322 of the local hazard planning regulations, the final plan will be adopted by
each of the jurisdictions as well as the county. This section documents the adoption process of each local
Page 13 of 252
government in order to demonstrate compliance with this requirement. The plan will formally be adopted
following conditional approval of FEMA Region VII’s review.
Table 2.2 (1) identifies the local governments that participated in the planning process and will adopt the
plan. According to the participation components set by the MPC (see above Requirements, Section 2.1
Participants), these jurisdictions have met satisfactory participation requirements of this hazard mitigation
plan. Resolutions from each Jurisdiction adopting the Plan listed in Table 2.2 (1) are provided in the
Appendix.

2.3 Documentation of the Planning Process
Multihazard Requirement §201.6(c)(1): [The plan shall document] the planning process used to develop the
plan, including how it was prepared, who was involved in the process, and how the public was involved.
The Pottawatomie County Multi-Jurisdictional Mitigation Plan is the result of a collaborative effort
between Pottawatomie County citizens, public agencies, and regional, state, and federal organizations.
Public participation played a key role in development of goals and mitigation projects. Interviews were
conducted with the Pottawatomie County Emergency Coordinator, mayors, elected officials, and other
organizations in the jurisdiction, and two public meetings were held to include the input of Pottawatomie
County residents.
In order to effectively notify the adjoining counties and invite them to contribute to the planning process,
the Emergency Manager for each county was notified via mail and/or email. In Kansas, the Emergency
Manager for each county has been designated as the county point-of-contact for Mitigation Planning.
Each Emergency Manager is responsible to report to its Commissioners, and other administrative entities,
regarding any activity necessary to comply. Invitations to apply for the FEMA and State funded grants for
Mitigation Planning were sent to the 105 Emergency Managers in Kansas as the designated
point-of-contact for each County Commission.
Entities listed in the appendix under the Initial Contact List were notified or contacted for every meeting
Page 14 of 252
conducted as part of the planning process. In addition, the Smoke Signal Newspaper was used to do public
notification. The Smoke Signal Newspaper is a regional publication with circulation in adjoining counties.
Pottawatomie County utilized the process recommended by the Kansas Division of Emergency
Management (KDEM) to develop this Multi-Jurisdictional Mitigation Plan. Pottawatomie County’s
mitigation planning process was initiated on June 2, 2008, when the county awarded a contract to EFM
Consulting, LLC. The mitigation planning process was completed over a twenty-one month time period,
with final draft completion in March 2010.
A comprehensive hazard analysis was conducted prior to mitigation planning, and was completed in 2007.
The hazard analysis is a comprehensive assessment and prioritization of risks and vulnerability in the
county, and forms the basis for this plan. The assessment is published electronically as a stand-alone
document consisting of 12 sections, and forms the basis for this mitigation plan.
Pottawatomie County developed this Multi-Jurisdictional Mitigation Plan in coordination with E-Fm
Consulting, LLC. Funding was provided by FEMA and the State of Kansas via a grant through the Kansas
Division of Emergency Management. The overall process to prepare this mitigation plan was developed
by E-Fm Consulting, LLC, Pottawatomie County Emergency Management, and the Pottawatomie
Mitigation Planning Committee.
Planning
E-FM Consulting was retained to represent Pottawatomie County as plan author, and provide support
services to develop the mitigation plan. E-Fm utilized the natural hazards data prioritized as part of the
Hazard Analysis in coordination with the MPC based on likelihood and severity for the jurisdiction. These
data were used to develop the goals, objectives, and mitigation strategy for Pottawatomie County.
Chris Trudo, Pottawatomie County Emergency Management Coordinator, served as the primary official
contact for the county. The MPC consisted of representatives from local government agencies, private and
public entities, and local businesses interested in the planning process. The Pottawatomie County MPC
conducted meetings and numerous in-house discussion sessions over the course of the planning process. A
number of officials at the federal, state, and local government level were contacted throughout the
planning process for specific information and technical expertise.
The Pottawatomie County MPC met on January 27, 2009, to review and approve the natural hazards and
vulnerability prioritization assessment. The indexed (prioritized) hazards were discussed, and a wide
range of mitigation actions were identified for high and moderate hazards and disseminated to committee
members for further discussion and approval prior to the first public meeting for the county. FEMA
categories for actions were also discussed in relation to projects and actions, with emphasis on
implementation capabilities at the local level for prioritized projects/actions. In addition, the Mitigation
Planning Committee members were provided electronic access to the county's draft plan for review and
comment on the overall draft strategy to assist with development of projects and actions for each
jurisdiction. Packets were distributed to attending sub-jurisdictions to assist with development of projects
and actions. Maps, as available, were discussed and distributed for vulverability assessment. Over the next
twelve months the MPC reviewed the draft data and provided comment/changes to further define the plan
strategy.
The first public meeting was held on February 9, 2010, to present the county draft plan to the MPC and
interested parties in the community. A review of the county and participating jurisdictions was followed
by a question and answer period. Forms were provided for the public to provide written comment to the
MPC. Notification of the first public meeting was provided by the following newspaper publications:
Smoke Signal (January 27, 2010), Wamego Times (January 28, 2010), Onaga Herald (January 28, 2010),
and the St Marys Star (January 27, 2010). Other advertisement included the following local television
stations: Blue Valley TV Channel 2, and Wamego Telecommunications Channel 3. E-Fm Consulting,

LLC, provided additional mail invitations via postcard on January 26, 2010. The MPC did not receive any
written comment from the public over the two-week review period.
The second public meeting was held on March 2, 2010, to present the final county draft plan to the MPC
and interested parties in the community. A review of the county and participating jurisdictions was
followed by a question and answer period. Forms were provided for the public to provide written
comment to the MPC. Notification of the second public meeting was provided by the following
newspaper publications: The Smoke Signal (February 24, 2010), and local advertisements on the
following television stations: Blue Valley TV Channel 2, and Wamego Telecommunications Channel 3.
Advertising dates were February 19th, 2010 through March 2nd, 2010. E-Fm Consulting, LLC, provided
additional mail invitations via postcard on February 19, 2010. The MPC did not receive any written
comment from the public over the two-week review period.
Meeting sign-in logs, jurisdictional authorization forms, and public comment forms (if any) can be found
in the appendix.
Public Participation
Efforts were made to solicit public input throughout the planning process using announcements and public
notification via local newspaper publications, and meeting notifications by first-class mail, phone, and
email. Two public meetings were held to obtain input from the community, which included notice to
businesses, non-profits, government agencies, and any others interested in the planning process.
Additionally, the Emergency Management Coordinator scheduled meetings with interested parties within
the county to review planning, code, land plan and flood zone planning initiatives in other departments.
Public input was solicited by direct written notices and announcement of the mitigation planning process,
with public meeting schedules announced two weeks prior to convening. No written comments were
received from the general public for the Pottawatomie County Mitigation Plan during the planning
process.
The county provided a copy of the final draft document for public review at the County Emergency
Operations Office and public library prior to presentation of the final draft plan at the second public
meeting. The draft Plan was also available online for review. The participating jurisdictions and the
County Commission tentatively approved the plan for submittal to the State Mitigation Officer March
2010, at which time no further public and private comment was received.
Summary
In short, the process included the following steps, listed in the order in which they were undertaken:
1. Natural Hazards Identification and Risk Assessment 2. County Vulnerability Assessment 3.
Mitigation Capabilities Assessment 4. Mitigation Strategy (Goals, Objectives, and Actions) 5. Plan
Maintenance
Step 1, the hazard identification and assessment, describes and analyzes the natural phenomena present in
Pottawatomie County that can threaten human life and damage property. It includes historical data on past
hazard occurrences, and establishes hazard profiles and risk indices based upon hazard frequency,
magnitude and impact. The risk rating forms the basic foundation for focusing and prioritizing mitigation
efforts.
Step 2, the county vulnerability assessment, was completed predominantly through investigative research
along with the use of available data at the time of the study. It includes narrative descriptions on
community characteristics, such as Pottawatomie County’s geographical, economic, and demographic
profiles, and discusses future development trends and implications for hazard vulnerability. To graphically
depict hazard vulnerability, this section also included readily-accessible county vulnerability assessment
maps.
Page 16 of 252
Step 3, the mitigation capabilities assessment, provides a comprehensive examination of Pottawatomie
County’s capacity to implement meaningful mitigation strategies, and identifies existing opportunities for
program enhancement. Capabilities addressed in this section include staff and organizational capability,
technical capability, policy and program capability, fiscal capability, legal authority and political
willpower. The purpose of this assessment is to identify any existing gaps, weaknesses or conflicts in local
programs/activities that may hinder mitigation efforts, or to identify those local activities that can be built
upon in establishing a successful county hazard mitigation program.
Steps 1, 2, and 3 form the basis for designing the community’s hazard mitigation strategy.
Step 4, the conclusion of Steps 1, 2, and 3, results in the formation of jurisdiction strategy and sets the
stage for developing and adopting a meaningful hazard mitigation plan for Pottawatomie County. These
four steps help make the plan strategic and functional for implementation purposes.
Step 5, which follows the completion of the mitigation strategy, concentrates on designing measures to
confirm the plan’s ultimate implementation, and adoption of evaluation and enhancement procedures for
routine updating.

The 2005 Kansas Land Cover Patterns map produced by the Kansas Applied Remote Sensing (KARS)
program provides a fairly accurate assessment of 11 land use/land cover classes. The bulk of the land
cover in the county (81.99%) is comprised of cropland and grassland. The primary water bodies include
Tuttle Creek Lake, Pottawatomie State Lake No.1, Pottawatomie State Lake No.2, and Lebo Lake. Urban
residential and urban industrial/commercial development comprises roughly 1.4% of the land cover,
primarily in and around the cities of Wamego, St. Mary's, and Onaga, with smaller populations in
Westmoreland, St. George, Wheaton, Olsburg, Louisville, Havensville, Emmett, and Belvue. Woodlands
are typically clustered along the many streams and creeks that traverse through the county. The principle
varieties of native timber are the walnut, oak, hickory, cottonwood and sycamore.
History
William G. Cutler’s History of Kansas, first published in 1883, tells about the history of Pottawatomie
County.
The first white people to settle within the borders of the county were Catholic missionaries who went to
St. Marys a few weeks preceding the immigration of the Pottawatomie Indians to their reservation, of
which St. Marys was a central point. This was in 1848. The mission and a log house near it were built the
same year. The Indians contributed to the erection of the mission school, which was 15 years in advance
of the common schools. A band of Michigan Pottawatomies joined their tribesmen on the reservation in
1850. In 1853 the population consisted of the Catholic missionaries, a few traders, 5 government
employees, and the following settlers: Dr. L. R. Palmer and his family, Alexander Peltier, Basil Germore,
William Martell, Francis Bergeron, Antoine Tescier, J. B. Frapp, Robert Wilson and family, Joseph
Truchey, Alva Higbee, O. H. P. Polk, Baptiste Ogee, Mrs. Zoe Durcharm, Mrs. E. A. Bertrand, Mrs. A. P.
Bertrand and Mrs. Clara Bertrand.
Early Settlers included: William Martell, Antoine Tasier, Bazile Greenmore, Francis Bergen, Robert
Wilson, A. Higben, Joseph Truckee, O. H. P. Polk, Baptise Ogee, Mrs. B. H. Bertrand, Mrs. Joseph
Bertrand, Mrs. Amable Bertrand, now the wife of Dr. L. R. Palmer, Zoa Durcharm, now Mrs. Wilson,
were the earliest settlers of what is now Pottawatomie County. They were here years before the passage of
the Kansas-Nebraska bill. Robert Wilson took the first claim in 1853, on the land where now stands
Page 20 of 252
Louisville, and here he erected the first house in the county outside the Pottawatomie reserve. It was used
as a hotel for many years. Judge Huggins and Dr. Sabin erected the first flouring mill that was run in the
County, in 1856. The first white child born in the county was Frank X. Palmer, son of Dr. Luther R. And
Mrs. Helen L. Palmer. Luke Lea, of Mississippi, was the first Indian Agent stationed at St. Mary's.
The county takes its name from the Pottawatomie tribe of Indians, whose reservation at the opening of
Kansas Territory for settlement, and for years afterwards embraced a large portion of the lands of the
county. In the latter part of the year, 1856, a petition drawn by Dr. Luther R. Palmer, the Government
physician at St. Mary's Mission, and signed by himself and a few other settlers, was addressed to the
Legislature, asking for the organization of a new county to be names Pottawatomie, Charles Jenkins and J.
A. J. Chapman being appointed to present the petition to the Legislature.
The petition was granted, and on the 23 of February, 1857, Governor Geary appointed Robert Wilson,
Probate Judge; George W. Gillespie and Charles Jenkins, County Commissioners, and J. L. Wilson,
Sheriff. The first Commissioners' Court convened at St. George, March 21, 1857, Judge Wilson,
Chairman, ex-officio, and appointed L. R. Palmer, County Clerk; Josiah D. Adams, Treasurer; J. A. J.
Chapman, Surveyor, and W. L. Seymour, Coroner. April 20, 1857, the Board of Commissioners appointed
James S. Gillespie, County Assessor, and divided the county into the four townships of Pottawatomie, St.
George, Blue and Shannon.
August 17, 1857, Jacob Emmons was the Probate Judge and Clerk of the Commissioners' Court, and on
September 21, two municipal townships were formed, named Vienna and Louisville. At the meetings
appointed for October 19, November 16, December 21, 1857, and January 18, 1858, there was no quorum
present. February 21, 1858, Thomas R. Points was appointed Commissioner, and on March 15, William
C. Dyer was appointed Sheriff.
The county is divided into 23 townships: Belvue, Blue, Blue Valley, Center, Clear Creek, Emmett, Grant,
Green, Lincoln, Lone Tree, Louisville, Mill Creek, Pottawatomie, Rock Creek, Shannon, Sherman, Spring
Creek, St. Clere, St. George, St. Marys, Union, Vienna and Wamego. The towns and villages are: Arispie,
Belvue, Blaine, Broderick, Emmett, Flush, Fostoria, Garrison, Havensville, Holy Cross, Laclede,
Louisville, Moodyville, Myers Valley, Olsburg, Onaga, St. Clere, St. George, St. Marys, Springside,
Wamego, Westmoreland and Wheaton.
3.2 Government
Pottawatomie County consists of a representative three-member commission. There are a total of eleven
incorporated jurisdictions within the boundaries of the county, each having a mayoral or mayor/city
council form of government.
A small portion of the City of Manhattan lies in Pottawatomie County. For this mitigation plan, this small
incorporated area is considered a part of Manhattan and is included in the Riley Couty Mitigation Plan.
The City of St. Marys lies in both Pottawatomie and Wabaunsee counties, however, the majority of St.
Marys lies within Pottawatomie County and is included in this Plan.
3.3 Demographics
Pottawatomie County is a Densely-settled Rural county located near a large population area (Manhattan),
and its economy is primarily agricultural. Pottawatomie County’s retail trade pull factor of 1.495% in
central Kansas for the year 2006 is currently ranked 1st in Region III. Pottawatomie County is actively
seeking ways to increase expansion of its existing businesses and industries in the county in an attempt to
broaden the tax base while not destroying the agricultural base of the county. From a production basis,
agricultural products (crops and livestock) comprise the majority of industry in the region.
Page 21 of 252
Pottawatomie County is one of the state's mid-sized counties in terms of total land area. Pottawatomie
County’s current population of 19,220 (2006 - US Census Estimated Population) ranks 29th out of 105
counties in the state. Most of these residents are dispersed throughout the county’s two (2) main
population centers, with some smaller concentrations residing in rural parts of the county. The average
population density for the entire county is 22.7 people per square mile of land.
REGIONAL POPULATIONS IN POTTAWATOMIE COUNTY (Certified to the Secretary of State-7-1-07)
Pottawatomie County is experiencing a population gain, which has been occurring since 1970. The recent
2006 U.S. Census estimated population for the county is 19,220, revealing an increase of 5.55% over the
2000 Census, but overall, the last 100 years have shown Pottawatomie County with only a small net

Economic Summary
Pottawatomie County’s overall increasing population makes economic development somewhat easier than
in other areas in the state, as the county is located close to a major Kansas micropolitan area for direct
access to major services. Pottawatomie county is classified as a Densely-Settled Rural county.
The Kansas Department of Health and Environment (KDHE) classifies counties into one of five tiers:
Frontier, Rural, Densely-settled rural, Semi-urban, and Urban. The classifications are based on several
factors including population per square mile. Since the 1930’s, Frontier/Rural contraction has been a
reality for the State. Frontier classification obviously represents the most economically disadvantaged and
Page 25 of 252
Urban the most prosperous. Frontier and Rural are considered "distressed" based on various economic and
demographic characteristics. A Frontier County is defined as those with less than 6.0 persons per square
mile; Rural counties are those with 6.0 – 19.0 persons per square mile.
Distressed counties (Frontier and Rural) account for 68 of the 105 counties in the State. Numerous bills
have been introduced into the Kansas legislature over the past ten years, but none have passed that
specifically addresses dwendling populations in the rural counties. Other suggestions have included
replacing irrigation-based agriculture with more diverse forms of economic activity. Ultimately, the
availability of steady, well-paying jobs and affordable housing would mitigate many of the problems
created by sparse population.
3.5 Climate
Pottawatomie County is included in the part of a region in which the climate is marked by extremes of
precipitation and temperature. Weather Bureau records show that the annual precipitation has ranged
between 17 and 47 inches and that the temperature has ranged from -32' to 115' F. The amount of rainfall
varies greatly from year to year and occasional droughts are experienced. The summers of 1930, 1934,
and 1936 were extremely dry, and farm crops suffered serious damage. The average growing season (from
last to first killing frost) extends from April 20th to October 9th (Carter and Smith, 1908, p. 10). Weather
averages are provided in Table 3.5 (1).

3.6 Natural, Historic, and Cultural Resources
Pottawatomie County is blessed with bountiful natural resources, which make the county a haven for
naturalists and outdoorsmen. Although Pottawatomie County does not have any National Wildlife
Refuges, there are fishing and wildlife areas, open lands, and miles of trails and back roads that provide
opportunities for unmatched outdoor experiences such as biking, water recreation, freshwater fishing, bird
watching, and hunting, to name a few.
The area’s most abundant natural resource may arguably be the agricultural land. Streams and creeks
criss-cross the county and the Kansas and Big Blue rivers serve as the county’s main water source. The
area experiences approximately 33.1 inches of rainfall on an annual basis. The quality of soil and suitable
drainage makes it possible to produce a variety of crops. Corn, oats, soybeans, and wheat make up the
majority of crops in the county. The total number of cropland harvested in 2006 was 142,200 acres.
Today, the Tuttle Creek Lake is the largest and most significant man made ecological resource in the
Page 26 of 252
county. The Kansas Water Office identified Tuttle Creek Lake (shared with Riley County), located within
the Lower-Republican River Basin, as a Multipurpose Large Lake. Its primary purpose is floodwater
detention and sediment storage, water supply, recreation, fish and wildlife conservation, water quality
control and downstream navigation supplementation.
Oil and Gas
The most recent reported quantity of annual oil production in Pottawatomie County was 2008, when three
wells produced 1,693 barrels of crude oil over a twelve-month period. Review of the Kansas Geological
Society oil and gas well database indicated that three oil wells are currently in production in Pottawatomie
County, with a reported quantity of 781 barrels, based on incomplete data as of the date of the report,
2009. Gas in commercial quantities has not been produced in the county for at least fifteen years.

3.7 Geologic Features
Topography and drainage
Topography
Pottawatomie County is located within two major land resource areas within the Central Lowlands
Physiologic Province. The majority of Pottawatomie County is located in the Bluestem Hills, with the
eastern segment of the county lying within the Cherokee Prairies land resource areas. Elevation ranges
from 300 to 500 m. These dissected limestone and shale uplands have narrow divides and narrow
steep-sided valleys. Only a few large streams have a significant area of flood plain. Local relief is
commonly in meters or tens of meters.
The highest elevation in the county, at 1,507 feet above sea level, is at Blane, located in the north-central
portion of the county. The town of Belvue, located in the southeast portion of the county, is situated at the
lowest elevation in the county, at approximately 960 feet above sea level. Belvue resides to the southeast
of the confluence of the Red Vermillion and East Rock Creek streams leading into the Kansas River.
Drainage
The Kansas-Lower Republican River Basin covers most of Pottawatomie County. The exceptions include
the extreme southeast corner that lies within the Neosho River Basin, and the southwest corner, which lies
within the Marias des Cygnes River Basin. The Kansas-Lower Republican covers nearly 10,500 square
miles of northeastern Kansas. The basin includes all or part of 24 counties. The basin has the largest
population of all the twelve major river basins, with an estimated 1,025,644 residents in the year 2000.
The population is projected to grow to nearly 1,531,000 in the year 2040.
Major streams within the basin include the Kansas, Republican, Big Blue, Little Blue, Delaware and
Wakarusa rivers, and the Vermillion and Stranger creeks. The major reservoirs in the basin are Lovewell,
Milford, Tuttle Creek, Perry and Clinton.
Most of the western part of Pottawatomie County is drained by the Big Blue River and its tributaries. The
East Fork Rock Creek and Red Vermillion creek drains the central and eastern portions of the county
respectively. The Big Blue touches the county at its northwest corner, separating it from Riley County;
starting in a southwesterly direction, its farthest west point is reached at about Kansas 16 Highway, then
the course is southeasterly to is mouth at Manhattan in Riley County. Its northwestern tributaries are
Spring Creek with eastern branches, and the Four Miles as a western branch; the Shannon, Carnahan,
McIntire, Cedar and Elbow creeks. The Kansas River forms the southern boundary of the county, its
principal tributary in the county being the Red Vermillion, which has its source in Nemaha County, enters
Pottawatomie from the northeast, runs southwesterly, and empties into the Kansas in Bellevue Township.
Its tributaries from the west are French and Mill creeks. Others are Coal, Indian, Adam, Rock Bush,
Darnell, Cross Clear and Pleasant Run creeks.
The National Resource Conserve Service (NRCS) identified three watersheds located in Pottawatomie
County within the Kansa-Lower Republican River Basin: Upper Kansas; Middle Kansas; and the Lower
Big Blue. Pottawatomie County has also been identified as a priority community in the Kansas-Lower
Republican Basin for future floodplain planning and mapping.
Rivers, Lakes, Streams
The Big Blue and Kansas Rivers make up the primary water sources in Pottawatomie County. Besides the
Big Blue and the Kansas rivers, which form the western and southern boundaries, there is the Vermillion
flowing south through the eastern portion of the county and emptying into the Kansas. Its tributaries from
the west are French and Mill creeks, and the tributaries of the Big Blue are Spring creek with eastern
branches, and Four Mile creek as a western branch, with Shannon, Carnahan, McEntire, Cedar and Elbow
creeks contributung to the west section.

The Kansas Water Office identified Tuttle Creek Lake (shared with Riley County), located within the
Lower-Republican River Basin, as a “Multipurpose Large Lake”. Tuttle Creek Lake is located in the
southwest portion of the county and is five miles north of Manhattan. Its primary purpose is floodwater
detention and sediment storage, water supply, recreation, fish and wildlife conservation, water quality
control and downstream navigation supplementation. Tuttle Creek Lake has approximately 9,628 square
miles of drainage area above the dam. The original storage capacity of the "multi-purpose" pool was
425,312 acre-feet, with current estimated capacity of 253,265 acre-feet. The "flood pool" surface area is
approximately 53,050 acres.
Lake Elbo (Latitude: 39.23361 / Longitude: -96.48861 /: Elevation: 1116 ft), is formed by Lake Elbo Dam
on Elbo Creek in Pottawatomie County, Kansas and is used for recreation purposes. It was built in 1949.
It is owned by Lake Elbo Club, Inc. The dam is of earthen construction. Its length is 1200 feet. Maximum
discharge is 3000 cubic feet per second. Its capacity is 495 acre feet. Normal storage is 450 acre feet.
Pottawatomie County State Lake No.1 is located five miles north of Westmoreland or two miles south of
Blaine on Kansas highway 99. Of the 190 acres purchased, only 24 acres was flood for the lake. The
Maximum depth of the lake is 17 feet, with and average depth of 6 to 8 feet. The area has 166 acres of
wildlife area which is open to the public.
Pottawatomie State Fishing Lake No.2. The lake was created by a 1953 donation from Dr. and Mrs.
Robert L. Freidrich of Manhattan. The donation included 247 acres of Flint Hills land, specifically
dedicated to future development of a recreational lake and park. In 1955, the Department of Wildlife and
Parks completed the 75-acre lake.
Two springs were identified within Pottawatomie County and include: Blackjack Spring, and Scott
Spring.

3.9 Local Jurisdictions
3.9.1 Wamego (2007 Kansas Certified Population: 4,248)
Wamego is the largest city in Pottawatomie County, however, it does not serve as the county seat.
Wamego sits 15.1 miles south of Westmoreland, the county seat. Agriculture serves as the city's economic
mainstay. According to the United States Census Bureau, the city has a total area of 1.7 square miles, of
which, 1.6 square miles of it is land and 0.04 square miles of it (2.40%) is water.
In the early 1860's the discovery of gold near Denver brought many through Wamego on the Smoky Hill
Trail. In 1863 the Kansas Pacific Railroad began building the main line for passengers and freight bound
westward across the plains. Seizing this opportunity, The Wamego Town Company founded and laid out a
new town site - Wamego - along the proposed rail in 1866. Wamego was later incorporated in 1868. The
Page 34 of 252
founders offered the railroad land and cash to locate the Kansas Pacific division headquarters in the town
for a minimum of 20 years. A station, roundhouse, and shops evolved, which employed a considerable
number of people. For a time, Wamego served as the rail yard for the larger town of Louisville four miles
north, which was situated on the Oregon Trail. This situation soon changed, as did transportation
techniques. By 1874 Wamego had 28 businesses as opposed to the six in Louisville. In 1890 the Kansas
Pacific moved the division headquarters to Junction City.
Numerous additions to the town were made early on. Several residential additions were added between
1870 and 1874. The first bridge across the Kansas River, replacing early ferry systems, was built in 1872.
A seven span concrete bridge later replaced this bridge in 1928 (the current bridge was constructed in
recent times). The first water system was installed in 1899, and electric lights in 1906. The city parklands
were acquired in 1901. Wamego continues to thrive as a progressive small city facing an unlimited future.
As of the census of 2000 (US Census Bureau), there were 1,630 households, and 1,155 families residing
in the city, with 1,740 housing units. The racial makeup of the city was 96.75% White, 0.73% African
American, 0.35% Native American, 0.12% Asian, 0.78% from other races, and 1.27% from two or more
races. Hispanic or Latino of any race were 1.88% of the population.
There were 1,630 households out of which 38.3% had children under the age of 18 living with them,
56.7% were married couples living together, 10.8% had a female householder with no husband present,
and 29.1% were non-families. 25.1% of all households were made up of individuals and 11.8% had
someone living alone who was 65 years of age or older. The average household size was 2.57 and the
average family size was 3.09.
In the city the population was spread out with 29.4% under the age of 18, 8.9% from 18 to 24, 29.3% from
25 to 44, 17.8% from 45 to 64, and 14.6% who were 65 years of age or older. The median age was 34
years.
The median income for a household in the city was $38,115, and the median income for a family was
$46,017. Males had a median income of $29,881 versus $21,974 for females. The per capita income for
the city was $16,307. About 5.7% of families and 8.6% of the population were below the poverty line,
including 9.1% of those under age 18 and 18.0% of those age 65 or over.
The three largestest industries (by number of 2005 establishments) include: construction (43
establishments), health care and social assistance (24 establishments), and other services (22
establishments). The construction machinery manufacturing industry provides a high number of jobs in
the area, with estimated 2005 employment of 449 individuals. Other high employment industries include:
services for the elderly and persons with disabilities (375 employees), and farm and garden machinery and
equipment merchant wholesalers (192 employees).
USD 320 - Wamego provides two elementary schools, West Elementary (K-2) and Central Elementary
(3-5), Wamego Middle School (6-8), and Wamego High School (9-12) in the city.
3.9.2 St. Marys (2007 Kansas Certified Population: 2,233)
St. Marys is one of the larger communities in Pottawatomie County. St. Mary's was a stop on the
Oregon-California Trail. St. Marys is 25 miles southeast of Westmoreland, the county seat. Agriculture
serves as the economic mainstay of the city. According to the United States Census Bureau, the city has a
total area of 1.1 square miles, all land.
St. Marys is one of the most historically important communities in Kansas. St. Marys was founded in
1847, as a Jesuit Mission and tribal headquarters, serving the Pottawatomie tribe when that tribe was
moved from Sugar Creek reserve in eastern Kansas. St. Marys straddled the route of the
Oregon-California Trail, the Fort Leavenworth - Fort Riley Military Road and the Smoky Hill Trail.
From 1847 to about 1857, St. Marys was the "Cape Canaveral" of western migration along this leg of the
Page 35 of 252
Oregon-California Trail. Once a person left St. Marys in those years - there was not another settlement
until one reached Salt Lake, the California Gold Fields or the Willamette Valley in Oregon Territory,
journeys of thousands of miles. The only intervening vestiges of "civilization" were two small sparsely
manned army posts at Fort Kearney and Fort Laramie.
Not far from St. Marys, on the south bank of the Kansas River a few miles east, was the westerly-most
ferry across the river. Nearby was the site of Uniontown, a Pottawatomie village and trading post that was
savaged by cholera twice - thence burned and abandoned in 1859.
St. Marys was one of the last locations of Jesuit service to North American tribes, which began in the
1600's in Quebec and Montreal. St. Marys Mission was the Pottawatomie Tribal headquarters and service
center until the tribal lands were greatly reduced in about 1867. The Old Pay Station, an original building
that served to distribute annual annuity payments and conduct other business on behalf of the tribe in the
early days of St. Marys, still stands and is part of the St. Marys museum complex.
As of the census of 2000 (US Census Bureau), there were 818 total households, and 525 families residing
in the city, with 818 housing units. The racial makeup of the city was 95.18% White, 0.91% African
There were 818 households out of which 35.5% had children under the age of 18 living with them, 56.8%
were married couples living together, 9.2% had a female householder with no husband present, and 31.2%
were non-families. 29.7% of all households were made up of individuals and 12.4% had someone living
alone who was 65 years of age or older. The average household size was 2.83 and the average family size
was 3.61.
years.
Of the 1,240 people aged 25 and older, 89.5% had completed high school, 48.5% had completed at least
some college, 13.4% had a BA, and 5.4% had an advanced or professional degree.

construction (15 establishments), and other services (9 establishments). The electric power distribution
industry employs the most people, with an employment estimated of 375 employees. Other industries with
high employment include other building material dealers (182 employees) and religious organizations (92
employees).
Kaw Valley USD 321 serves the communities of St. Marys, Emmett, in Pottawartomie County, and Delia

St. Marys private school includes St. Marys Elementary, and St. Marys Junior/Senior High School.
3.9.3 Westmoreland (2007 Kansas Certified Population: 737)
Westmoreland is the county seat of Pottawatomie County. The City of Westmoreland's economy is largely
derived from agriculture. According to the United States Census Bureau, the city has a total area of 0.5
square miles, all of it land.
Westmoreland has a rich history. Virtually the entire townsite of Westmoreland and much of the
immediate surrounding area was part of the Scott Springs campsite on the Oregon - California Trail. This
Page 36 of 252
famous site was used for almost 30 years between the 1840's and 1870's by hundreds of thousands of
emigrants. These emigrants were bound for Salt Lake, the California Gold Fields or the Willamette Valley
in Oregon Territory.
Today, Westmoreland contains a number of historic buildings. The Pottawatomie County Courthouse,
built of native limestone in the 19th century, is in the center of town. A historical museum complex is
maintained by the Rock Creek Valley Historical Society, and it includes actual historic log and stone
buildings, replicated buildings and a rich collection of artifacts and documents commemorating the
Oregon-California Trail and early settlement of the Westmoreland area.
As of the Census of 2000 (US Census Bureau), there were 262 households, and 171 families residing in
the city, with 293 housing units. The racial makeup of the city was 98.42% White, 0.32% Native
American, 0.48% from other races, and 0.79% from two or more races. Hispanic or Latino of any race
were 1.58% of the population.

years.
The three most established industries include professional, scientific, and technical services (6
establishments), transportation and warehousing (5 establishments), and construction (5 establishments).
The nursing care facilities industry employs the most people with an estimated employment of 75
individuals. Other industries with high employment include: commercial banking (35 employees), and
veterinary services (15 employees).
Due to diminishing population and school consolidation, St. George participates in the Rock Creek USD
323 school district with Westmoreland. St. George hosts St. George Elementary School and the Rock
Creek Junior/Senior High School. Westmoreland supports the district's other grade school.
3.9.4 Onaga (2007 Kansas Certified Population: 673)
Onaga is located 21.56 miles northeast of Westmoreland, the county seat. Agriculture serves as the
economic mainstay of the community. According to the United States Census Bureau, the city has an area
of 0.6 square miles, all land.
Onaga sits on the upper reaches of the (Red) Vermilion River valley. Native Americans used the valley
for millennia. Evidence of extensive habitation and use of the area by successive groups of indigenous
people was documented by the Kansas State Historic Society in the 1950's and 60's.
More recently, in the 18th and early 19th centuries, the area was used primarily by the Konza Tribe. In the
1830's the area became part of the "Delaware Outlet" which afforded a route for the Delaware Tribe in
Eastern Kansas to access the buffalo herds to the west. In 1847 the Pottawatomie Reservation was
established, centered in St. Marys to the south. The northern boundary of this 900 square mile reservation
was just south of Onaga. By 1870 the Delaware and Konza had been moved to Indian Territory
(Oklahoma), while the Pottawatomie reservation was much reduced to its current size.
Page 37 of 252
European settlement began in the Onaga area in the 1850's and was much increased after the Civil War.
Many of the early settlers in the area were French, Irish, Swiss, German and "Pennsylvania Dutch". They
were mainly engaged in ranching and agriculture on the surrounding prairies and valleys. Most of the land
around Onaga remains in agricultural and ranching use today. Direct descendants of many of the original
pioneer families still live in the Onaga area. It is not uncommon for 5th and 6th generation descendants to
still occupy the original lands homesteaded by their fore bearers in the vicinity of Onaga.
Onaga was platted in 1877, by Paul E. Havens, President of the Kansas Central (Railroad) Town
Company. There was an additional plat added in 1878. At the time of the formation of Onaga, only two
families lived on the site; the Hubbells and the Landons. Onaga, like many rural Kansas towns, flourished
as a regional agricultural support center for many decades, a role it still plays today.
As of the census of 2000 (US Census Bureau), there were 292 households, and 162 families residing in
the city, with 347 housing units. The racial makeup of the city was 96.73% White, 0.28% African

years.
The general medical and surgical hospitals industry provides an estimated employment of 175 individuals
(2005). Other high employment industries are commercial banking (75 employees) and trust, fiduciary,
and custody activities (35 employees). The three most established industries are retail trade (8
establishments), health care and social assistance (5 establishments), and accommodation and food
services (4 establishments).
USD 322 (Onaga-Havensville-Wheaton) school district serves Onaga. Onaga hosts the Onaga Grade
School and Onaga High School.
3.9.5 St. George (2007 Kansas Certified Population: 505)
St. George is located 14.2 miles southwest of Westmoreland, the county seat. St. George's economy is
mainly derived from agriculture. According to the United States Census Bureau, the city has a total area
of 0.4 square miles, all of it land.
St. George lies not far from the confluence of the Blue and Kansas Rivers. For centuries the area was used
by many American Indian tribes as a hunting ground and as an area in which to work some cultivated
crops, due to the enormously fertile ground along the rivers.
The earliest Europeans thought to have entered the area around St. George were French in 1724,
according to an old publication entitled "A French Expedition Through Kansas." The earliest known
American incursions to the area were the Long Expedition in 1819, followed by Fremont in 1842.
Between that time, it is likely that additional Americans visited the area on their way to other places.
During much of the first half of the 19th century the area around St. George was firmly in the possession

of the Konza Indians, although there were periodic incursions by Pawnee, who used the Republic and
Blue River valleys as invasion routes into the fertile Kansas River Valley.
St. George was platted in 1857 - the first town to be platted in what became Pottawatomie County. Since
it was the first - it was also designated the original county seat - a status which it lost in 1862 to the town
of Louisville.
The Union Pacific railroad reached St. George in 1866. In 1877 a ferry was at St. George across the
Kansas River. By the turn of the century - some internal combustion powered vehicles had begun to
appear. Old Highway 40 which ran through St. George, was paved for automobile traffic in 1928. It is still
extremely easy to get from St. George to either Manhattan or Wamego via old Hwy. 40 - and- along the
new four-lane US Hwy. 24.
As of the census of 2000 (US Census Bureau), there were 173 households, and 106 families residing in
the city, with 198 housing units. The racial makeup of the city was 97.47%,White all of them related,

The wood kitchen cabinet and countertop manufacturing industry provides an estimated employment of
15 individuals (2005). Other industries in the area that provide a high number of jobs are full-service
restaurants (15 employees), and masonry contractors (15 employees). The three most established
industries are construction (6 establishments), accommodation and food services (5 establishments), and
retail trade (2 establishments).
Due to diminishing population and school consolidation, St. George participates in the Rock Creek USD
323 school district with Westmoreland. St. George hosts St. George Elementary School and the Rock
Creek Junior/Senior High School. Westmoreland supports the district's other grade school.

Belvue is located 25 miles southeast of Westmoreland, the county seat. Belvue's economy is largley based
on agriculture. According to the United States Census Bureau, the city has a total area of 0.1 square miles,
all of it land.
A brief synopsis of early Belvue is transcribed from Cutler's History. Belvue township is one of the
southern tier of townships on the Kansas River. Its chief point of interest is Belvue, a thriving young
village on the main branch of the Kansas Pacific. This village was laid out by A. J. Baker and Malcolm

Louisville is located 11 miles southeast of Westmoreland, the county seat. Agriculture is the economic
mainstay for the community. According to the United States Census Bureau, the city has a total area of
0.5 square miles, all of it land.
Louisville was originally known as Rock Post and was located near the Oregon Trail. The town was
Page 40 of 252
platted in 1857 and was named Louisville in honor of Louis Vieux and Louis Wilson. The town was a
contender for county seat of Pottawatomie County but lost to St. George and Westmoreland.
On November 8, 1875, Louisville was struck by an earthquake. Throughout the 1880s Louisville's
population declined. In 1882 the county seat was officially moved to Westmoreland and a majority of
people moved either there or to Wamego.
Louis Vieux was a prominent citizen of Louisville who operated a trail crossing across the Vermillion
River. He also made many trips to Washington, D.C. representing the Pottawatomis. When he passed
away in 1872 he was a very wealthy man and bequeathed the entire town of Louisville to his wife and
children. His name was also used in the naming of Belvue and is honored on an elm tree about three miles
east of Louisville. The elm tree, now destroyed by weather, Dutch Elm disease and vandalism, was once
the largest elm tree in the United States.

3.9.9 Olsburg (2007 Kansas Certified Population: 192)
Olsburg is located 14 miles west of Westmoreland, the county seat. According to the United States Census
Bureau, the city has a total area of 0.2 square miles, all of it land.
Olsburg lies just a few miles east of the upper end of Tuttle Creek Reservoir on the Blue River. Prior to
European settlement, the fertile Blue River valley was continuously occupied and used for millennia by
successive waves of Native Americans dating back to approximately 8-10,000 BC. In the late 18th and
early 19th centuries the area was used primarily by the Konza Indian tribe, which had a major village
some 25 miles south near what is now Manhattan. It is believed that the area around Olsburg was
sometimes in dispute between the Konza and the Pawnee.
Early explorers included the French in the 18th century. An 18th century French map of the area shows a
Konza settlement in the area now covered by Junction City. In 1806 Zebulon Pike passed not far south of
the Olsburg area on his first exploratory expedition. The area around Olsburg was first settled by a few
intrepid American settlers who claimed land along the fertile creek and river bottoms. The earliest
settlements began prior to 1853 when Juniata Crossing was established on the Fort Riley Military Road.
Samuel Dyer, buried in the oldest grave in nearby Carnahan Cemetery was contracted with by the military
Page 41 of 252
to operate the ferry at the crossing in 1853. This crossing later became a stagecoach station on the
Butterfield Overland Dispatch route to Denver.
The cultural origins of early settlers in the Olsburg area included families from England, Scotland, and
Germany. The earliest founders of Olsburg City were primarily Swedish.
Olsburg itself was platted and officially born in 1880 when the Kansas Central Railroad ran its line
through the area and a general store was opened by Oscar and C.W. Fagerberg. Some descendants of the
original settlers of the Olsburg area still own and/or occupy farm and ranch lands in the vicinity.
As of the census of 2000 (US Census Bureau), there are 80 households, and 63 families residing in the
city. The population density is 1,282.7 people per square mile (494.2/km²). There are 85 housing units at
an average density of 567.9/sq mi (218.8/km²). The racial makeup of the city is 99.48% White and 0.52%
Native American.
There are 80 households out of which 26.3% have children under the age of 18 living with them, 68.8%
are married couples living together, 7.5% have a female householder with no husband present, and 21.3%
are non-families. 18.8% of all households are made up of individuals and 5.0% have someone living alone
who is 65 years of age or older. The average household size is 2.40 and the average family size is 2.75.
In the city the population is spread out with 21.4% under the age of 18, 9.9% from 18 to 24, 24.5% from
25 to 44, 17.7% from 45 to 64, and 26.6% who are 65 years of age or older. The median age is 42 years.
The median income for a household in the city is $37,969, and the median income for a family is $39,531.
Males have a median income of $27,386 versus $23,281 for females. The per capita income for the city is
$14,268. 5.0% of the population and 7.2% of families are below the poverty line. Out of the total
population, none of those under the age of 18 and 19.1% of those 65 and older are living below the
poverty line.
In terms of total establishments in the city, the top three are professional, scientific, and technical services
(3 establishments), accommodation and food services (2 establishments), and arts, entertainment, and
recreation (2 establishments). The commercial banking industry provides a high number of jobs in the
area, with estimated 2005 employment of 15 individuals. Other industries with high employment are other
building material dealers (7 employees), and recreational and vacation camps (except campgrounds) (3
employees).
USD 384 - Blue Valley serves the communities of Olsburg in Pottawatomie County, and the town of
Randolph in Riley County. Olsburg hosts the Olsburg Elementary School. Randolph hosts the Randolph
Middle School, and Blue Valley High School. USD 384 and Twin Lakes Educational Cooperative
(TLEC) also offers a 3 and 4 year-old preschool in Randolph.
3.9.10 Havensville (2007 Kansas Certified Population: 144)
Havensville is located 28 miles northeast of Westmoreland, the county seat. Agriculture serves as the
economic mainstay of the community. According to the United States Census Bureau, the city has a total
area of 0.1 square miles, all of it land.

3.10 Mitigation Capabilities
This portion of the Plan assesses Pottawatomie County’s current capacity to mitigate the effects of the
natural hazards identified in Section 4.0. The assessment includes a comprehensive examination of the
following local government capabilities:
• Staff & Organizational Capability
• Administrative and Technical Capability
•
•
•
•
Page 43 of 252
Policy & Program Capability
Fiscal Capability
Legal Authority
Political Willpower
The purpose of conducting this capabilities assessment is to identify potential hazard mitigation
opportunities available to Pottawatomie County through its operation as a local government. Careful
analysis should detect any existing gaps, shortfalls or weaknesses within existing government activities
that could exacerbate jurisdiction vulnerability. The assessment will also highlight the positive measures
already in place or being done at the county level, which should continue to be supported and enhanced if
possible through future mitigation efforts.
The jurisdictions participating in this multi-jurisdictional plan believe it has the capacity to stand alone
and will, for most situations, execute it as such. In the cases where the jurisdiction indicates a
comprehensive plan, or related planning function, this plan will be used or incorporated in to that process
as a reference or guiding document. As part of plan maintenance, the yearly review will examine and
document the integration of the mitigation plan with other plans and planning functions. This process will
also review new opportunities to incorporate and integrate the plan.
The capabilities assessment serves as the foundation for designing an effective hazard mitigation strategy.
It not only helps establish the goals and objectives for Pottawatomie County to pursue under this plan, but
also ensures that those goals and objectives are realistically achievable under given local conditions.

3.10.1 Staff and Organizational Capability
Pottawatomie County has a part-time three-member elected commission. Commissioners are elected
through voter precincts (number of voters determined through district mapping, rather than as
representatives of each township). Terms on the board are four-year terms and are staggered with
elections held every two years.
Pottawatomie County is responsible for property tax valuation and collection to help support the operation
of the public school system. Taxes are paid to the state then re-distributed back to the county's school
districts based on formula. These funds generally maintain buildings, provide funds for capital projects,
and also include paying salaries, purchasing textbooks and supplies.
The county, in coordination and support from local municipalities, has a number of professionally staffed
departments and organizations to serve the residents of Pottawatomie County and to carry out day-to-day
Page 45 of 252
administrative activities. Additionally, the county does have staff and organizational resources in place
that are necessary to implement hazard mitigation strategies. These include the following:
The Pottawatomie Board of County Commissioners is responsible for applicable local codes through a
program of inspection and permitting.
The Board of County Commissioners, Treasurer, Register of Deeds, and the Sheriff are elected every four
years.
Appointed Positions include: Administration, Emergency Management Coordinator, Health Department
Administrater, Appraiser, Public Works, and GIS. Functional departments operate on a budget approved
annually by the commissioners.
The Pottawatomie County Cooperative Extension office seeks to help individuals, families, and
communities put research-based knowledge to work to improve their lives. Kansas’s Cooperative
Extension is based at Kansas's land grant institution, Kansas State University, but offices are located in all
105 counties in the State.
The Pottawatomie County Public Health Department seeks to help individuals, families, and communities
put research-based knowledge to work to improve their lives.
The Emergency Management office is responsible for the mitigation, preparedness, response and recovery
operations that deal with both natural and man-made disaster events. The formation of an emergency
management department in each county is mandated under Kansas General Statutes.
The Treasurer is responsible for the oversight and management of the County’s budget and fiscal
programs, including the administration of state and federal grants.
Of the above-listed county departments, the following are actively involved in mitigation activities or
hazard control tasks: Emergency Management, Fire, Health, GIS, and Public Works. Each of these
departments has been involved in hazard analysis and the development of mitigation planning for the
county in order to identify gaps, weaknesses or opportunities for enhancement of potential mitigation
programs.
For the most part, it was determined that each of these departments are staffed, trained, and funded to
accomplish their day-to-day missions. However, staff identified the need for expanded Information
Technology and GIS capability to enhance countywide-planning capabilities. This need is further
described in the mitigation actions.
City Government
All incorporated cities within Pottawatomie County reportd that they have very limited staff and
organizational resources to implement hazard mitigation strategies.
Wamego has a mayor and a five-member City Council. Council members are elected at large to four-year
staggered terms.

terms.
Westmoreland has a six-member elected City Council and mayor. Council members are elected at-large to
two-year staggered terms.
Belvue has a mayor and a five-member elected City Council. Council members are elected at-large to two
year terms, which are not staggered.
Emmett has a mayor and a five-member elected City Council. Council members are elected at-large for
four-year staggered terms.
Page 46 of 252
Havensville has a mayor and a five-member elected City Council. Council members are elected at-large to
two year terms, which are not staggered.
Olsburg has a five-member elected City Council and a mayor. Council members are elected at-large, and

serve for staggered three year terms.
St. George has a five-member elected City Council and a mayor. Council members are elected at-large,
and serve on the board for four-year terms, which are staggered with elections held every two years.
The Board of Education for each school district (USDs 320, 323, 321, 322, and 384) are responsible for
the operation of their respective school districts, and are elected at large by the people.
3.10.2 Legal and Regulatory Capability
In implementing a mitigation plan or specific action, a local jurisdiction may utilize any or all of the four
broad types of government authority granted by the State of Kansas. The four types are defined as: (a)
regulation, (b) acquisition, (c) taxation, (d) spending.
The scope of this local authority is subject to constraints, however, as all of Kansas political subdivisions
must not act without proper delegation from the State. Under a principle known as Dillon’s Rule, all
power is vested in the State and can only be exercised by local governments to the extent it is delegated.
Thus, this portion of the capabilities assessment will summarize Kansas’ enabling legislation which grants
the four types of government powers listed above within the context of available hazard mitigation tools
and techniques.
Regulation
General Police Power
Kansas local governments have been granted broad regulatory powers in their jurisdictions. Kansas
General Statutes (K.A.R.) bestow the general police power on local governments, allowing them to enact
and enforce ordinances which define, prohibit, regulate or abate acts, omissions, or conditions detrimental
to the health, safety, and welfare of the people, and to define and abate nuisances (including public health
nuisances).
Since hazard mitigation can be included under the police power (as protection of public health, safety and
welfare), towns, cities, and counties may include requirements for hazard mitigation in local ordinances.
Local governments may also use their ordinance-making power to abate nuisances, which could include,
by local definition, any activity or condition making people or property more vulnerable to any hazard.
Pottawatomie County (unincorporated) and the incorporated cities have enacted and enforce regulatory
ordinances designed to promote the public health, safety and general welfare of its citizenry. These
ordinances are discussed in this section.
Building Codes and Building Inspection
Many structural mitigation measures involve constructing and retrofitting homes, businesses and other
structures according to standards designed to make the buildings more resilient to the impacts of natural
hazards. Many of these standards are imposed through the building code.
Page 47 of 252
Kansas does not have state mandatory building codes. However, municipalities and counties may adopt
codes for their respective areas if approved by the state as providing “adequate minimum standards”.
Local governments in Kansas are also empowered to carry out building inspections, and may empower
cities and counties to create an inspection department to enforce construction codes and ordinances.
Regulatory powers granted by the state to local governments are the most basic manner in which a local
government can control the use of land within its jurisdiction. Through various land use regulatory
powers, a local government can control the amount, timing, density, quality, and location of new
development. All these characteristics of growth can determine the level of vulnerability of the
community in the event of a natural hazard. Land use regulatory powers include the power to engage in
planning, enacting and enforcing zoning ordinances, floodplain ordinances, and subdivision controls.
Each local community possesses great power to prevent unsuitable development in hazard-prone areas.
Pottawatomie County (unincorporated) has building codes which were recently adopted on January 5,
2009, as part of the Pottawatomie County Unified Development Resolutions (No. 2009-1). The City of
Wamego adopted the 2000 IBC, IRC, IPC, IMC, IFGC, IECC, IPMC, and 1999 NEC on June 1, 2004.
Wamego also adopted the 2000 IFC on February 5, 2002. The City of St. George adopted building codes
(Ordinance # 08-02) on April 2, 2008. The City of St. Marys adopted UPC and UBC building codes in
1991 and NEC codes in 1993. The City of Onaga adopted International Building Codes in 2006. The
cities of Westmoreland, Wheaton, Louisville, Belvue, Havensville, Emmett, and Olsburg reported that
they do not have building codes.
Planning
In order to exercise the regulatory powers conferred by the General Statutes, local governments in Kansas
are required to create or designate a planning agency. The planning agency may perform a number of
duties, which include the following: make studies of the area; determine objectives; prepare and adopt
plans for achieving those objectives; develop and recommend policies, ordinances, and administrative
means to implement plans; and perform other related duties. The importance of the planning powers of
local governments is emphasized in Kansas statutes, which require that zoning regulations be made in
accordance with a comprehensive plan. While the ordinance itself may provide evidence that zoning is
being conducted “in accordance with a plan”, the existence of a separate planning document ensures that
the government is developing regulations and ordinances that are consistent with the overall goals of the
jurisdiction.
Pottawatomie County, Wamego, and Westmoreland reported they do have an established Planning
Commission for guiding growth in their communities. The cities of St. George, Louisville, Emmett, St.
Marys, Onaga, Havensville, Belvue, Wheaton, and Olsburg reported that they do not have planning
committees for their communities.
County Ordinances
Pottawatomie County has implemented ordinances that are relevant to hazard mitigation. These
ordinances will be considered when developing this Plan’s Mitigation Strategy.
Page 48 of 252
Pottawatomie County has established an Emergency Management Department for protection of people,
property and environment within the county. The Pottawatomie Unified Development Resolutions were
adopted January 5, 2009, and outlines zoning, subdivision, stormwater, floodplain management,
permitting and building regulations in the county. Burn Ban Resolution #2006-84, was implemented
October 9, 2006 and provides the Emergency Management Director decision-making authority to
establish a burn ban based on the NOAA Fire Index Ratings for extreme conditions. Pottawatomie County
adopted a Floodplain Management Ordinance on October 23,1997, to promote the public health, safety,
and general welfare; to minimize loss in special flood hazard areas (SFHAs), and maintain the county's
eligibility for participation in the National Flood Insurance Program (NFIP).
City Ordinances
Wamego has enacted and enforces regulatory ordinances designed to promote the public health, safety
and general welfare of its citizenry. These ordinances include building codes, zoning ordinances,
subdivision regulations, a storm water management plan, a comprehensive land plan, and floodplain
management (NFIP membership).
Westmoreland - due to a smaller population and tax revenue base, there are few regulatory functions the
city enforces for hazard mitigation. Westmoreland reported that they are currently in the process of
developing both sub-division regulations and zoning and permitting ordinances for their community.
St. George has enacted and enforces regulatory ordinances designed to promote the public health, safety
subdivision regulations, a comprehensive land plan, and floodplain management (NFIP membership).
St. Marys has enacted and enforces regulatory ordinances designed to promote the public health, safety
subdivision regulations, a comprehensive land plan, and floodplain management (NFIP membership).
Olsburg - due to a smaller population and tax revenue base, there are few regulatory functions the city
enforces for hazard mitigation. Olsburg has passed zoning and permitting ordinances to help guide growth
in their community.
Onaga has enacted and enforces regulatory ordinances designed to promote the public health, safety and
general welfare of its citizenry. These ordinances include building codes, zoning ordinances, subdivision
regulations, and floodplain management (NFIP membership).
Emmett - due to a smaller population and tax revenue base, there are few regulatory functions the city
enforces for hazard mitigation, but they have enacted a Stormwater Management Plan, zoning and
permitting ordinances, and participates in the Highway 24 Corridor Plan (Comprehensive Land Plan).
Belvue - due to a smaller population and tax revenue base, there are few regulatory functions the city
enforces for hazard mitigation. Belvue reported regulatory ordinances are limited to a planning and zoning
department, and floodplain management (NFIP membership).
Louisville - due to the small population and tax revenue base, there are few regulatory functions the city
enforces other than participating in the Highway 24 Corridor Plan (Comprehensive Land Plan).
Havensville - due to the small population and tax revenue base, there are few regulatory functions the city
enforces. Havensville has not enacted any regulatory ordinances pertaining to mitigation activities.
Wheaton - due to the small population and tax revenue base, there are few regulatory functions the city
enforces. Wheaton has not enacted any regulatory ordinances pertaining to mitigation activities.
Zoning
Zoning is the traditional and most common tool available to local governments to control the use of land.
Kansas statutes grant municipalities and counties broad enabling authority to engage in zoning for land
Page 49 of 252
use. Counties may also regulate inside municipal jurisdiction at the request of a municipality. The
statutory purpose for the grant of zoning power is to promote health, safety, morals, and the general
welfare of the community. Land “uses” controlled by zoning include the type of use (e.g., residential,
commercial, industrial) as well as minimum specifications for use such as lot size, building height and set
backs, density of population, etc.
Local governments are authorized to divide their territorial jurisdiction into districts, and to regulate and
restrict the erection, construction, reconstruction, alteration, repair or use of buildings, structures, or land
within those districts. Districts may include general use districts, overlay districts, special use districts or
conditional use districts. Zoning ordinances consist of maps and written text.
Pottawatomie County (unincorporated) has adopted zoning regulations to enhance and manage growth in
their communities. Zoning regulations were adopted in 1962 and were most recently amended with the
adoption of the Pottawatomie County Unified Development Resolution in 2009. The City of Wamego
adopted zoning regulations in 2004 (Ordinance No. 1433, amending Ordinance No. 1117). The City of St.
George adopted zoning regulations (Ordinance Nos. 3471 & 3514) on August 1, 1984, and September 4,
2002 respectively. The City of St. Marys adopted zoning regulations (Ordinance No. 1172). The City of
Olsburg reported that it passed zoning regulations (Ordinance No. 329) on August 5, 1997, and amended
the regulaton (Ordinance No. 362) on June 6, 2009. The City of Onaga adopted zoning regulations
(Ordinance No. 445) in July 1972. The City of Emmett reported that they passed zoning and permitting
ordinances (Ordinance No. 29) on February 14, 1989. As of the writing of this plan, the City of
Westmoreland does not have any zoning regulations, but the city is in the process of developing zoning
regulations. The cities of Havensville, Belvue, Wheaton, and Louisville reported that they do not have any
zoning regulations.
Subdivision Regulations
Subdivision regulations control the division of land into parcels for the purpose of building development
or sale. Flood-related subdivision controls typically require that sub-dividers install adequate drainage
facilities and design water and sewer systems to minimize flood damage and contamination. They prohibit
the subdivision of land subject to flooding unless flood hazards are overcome through filling or other
measures, and they prohibit filling of floodway areas. Subdivision regulations require that subdivision
plans be approved prior to the division and/or sale of land. Subdivision regulations are a more limited tool
than zoning and only indirectly affect the type of use made of land and the specifications for structures on
that land.
Broad subdivision control authority resides with the county for areas outside of municipalities and
municipal extra-territorial planning jurisdictions. Subdivision is defined as all divisions of a tract or parcel
of land divided into two or more lots and all divisions involving new streets. Application and approval for
water meter installation play an important part in the planning process.
Pottawatomie County (unincorporated) has adopted several provisions that guide subdivision development
that are addressed in Article IV of the Pottawatomie Unified Development Resolutions (No. 2009-1). The
City of Wamego adopted subdivision regulations on August 1, 1997. The City of St. Marys adopted
subdivision regulations on February 8, 1988. The City of St. George included subdivision regulations in
Section 9 of the August 1, 1984 Zoning Regulations (Ordinance No. 3471). The City of Onaga first
adopted subdivision regulations (Ordinance No. 547) in March, 1993, and then ammended them
(Ordinance No. 597) in March, 2006. As of the writing of this plan, the City of Westmoreland does not
have any subdivision regulations, although, the city is in the process of developing subdivision regulation.
The cities of Olsburg, Louisville, Emmett, Havensville, Wheaton, and Belvue have not adopted
subdivision regulations.
Floodplain Regulation
In February of 1992, the Kansas General Assembly approved legislation for floodplain management
Page 50 of 252
(K.S.A. 12-766, entitled “Floodplain Management”) authorizing the Department of Agriculture, Division
of Water Resources, as the primary department to oversee and approve local zoning regulation. The
regulation requires planning and approval to prevent inappropriate development in the one hundred-year
floodplain and to reduce flood hazards (Reference Kansas Statute for details).
The purpose of the law is threefold: (1) minimize the extent of floods by preventing obstructions that
inhibit water flow and increase flood height and damage; (2) prevent and minimize loss of life, injuries,
property damage and other losses in flood hazard areas; and (3) promote the public health, safety and
welfare of citizens of Kansas in flood hazard areas. The new statute affects local governments by
directing, not mandating, them to do the following: (1) manage planned growth; (2) adopt local
ordinances to regulate uses in flood hazard areas; (3) enforce those ordinances; (4) grant permits for use in
flood hazard areas that are consistent with the ordinance. The act also makes certain that local ordinances
meet the minimum requirements of participation in the National Flood Insurance Program (NFIP).
The incentive for local governments adopting such ordinances is that they will afford their residents the
ability to purchase flood insurance through the NFIP. In addition, communities with such ordinances in
place will be given priority in the consideration of applications for loans and grants from the Clean Water
Revolving Loan and Grant Fund. Additional points may be awarded for actions taken toward the
implementation of a comprehensive land-use plan, such as the adoption of a zoning ordinance or any other
measure that significantly contributes to the implementation of the comprehensive land-use plan and the
flood management ordinance.
Pottawatomie County (unincorporated), and the cities of Onaga, Belvue, Wamego, St. George, and St.
Marys have adopted floodplain regulations to monitor and restrict development in suspected flood-prone
areas, and currently participate in the National Flood Insurance Program. The floodplain regulations are
outlined in Article X of the Pottawatomie Unified Development Regulations and require a floodplain
development permit for all proposed construction or other development, including the placement of
manufactured homes in all lands identified as unnumbered A zones, AE, AO, and AH on the Index Map
dated February 4, 1998 of the Flood Insurance Rate Map (FIRM). Permits will be granted by the
Pottawatomie Floodplain Administrator upon review of all applications for development in the floodplain.
Acquisition
The power of acquisition can be a useful tool for pursuing local mitigation goals. Local governments may
find the most effective method for completely “hazard-proofing” a particular piece of property or area is
to acquire the property (either in fee or a lesser interest, such as an easement), thus removing the property
from the private market and eliminating or reducing the possibility of inappropriate development
occurring. Kansas legislation empowers cities, towns, counties to acquire property for public purpose by
gift, grant, devise, bequest, exchange, purchase, lease or eminent domain (County Home Rule Powers,
K.S.A. 19-101, 19-101a, 19-212).
Pottawatomie County (unincorporated) has not used acquisition as a local mitigation tool, but has utilized
the use of elevation as a mitigation action. The cities of Wamego, Westmoreland, Louisville, Emmett,
Havensville, St. Marys, Belvue, Onaga, Olsburg, Wheaton, and St. George reported that they have not
used acquisition as local mitigation tool.
Taxation
The power to levy taxes and special assessments is an important tool delegated to local governments by
Kansas law. The power of taxation extends beyond merely the collection of revenue, and can have a
profound impact on the pattern of development in the community. Communities have the power to set
preferential tax rates for areas which are more suitable for development in order to discourage
development in otherwise hazardous areas.
Local units of government also have the authority to levy special assessments on property owners for all
Page 51 of 252
or part of the costs of acquiring, constructing, reconstructing, extending or otherwise building or
improving flood control within a designated area. This can serve to increase the cost of building in such
areas, thereby discouraging development.
Because the usual methods of apportionment seem mechanical and arbitrary, and because the tax burden
on a particular piece of property is often quite large, the major constraint in using special assessments is
political. Special assessments seem to offer little in terms of control over land use in developing areas.
They can, however, be used to finance the provision of necessary services within municipal or county
boundaries. In addition, they are useful in distributing to the new property owners the costs of the
infrastructure required by new development.
Pottawatomie County (unincorporated) and the cities of Wamego, Westmoreland, Louisville, Emmett,
Havensville, St. Marys, Belvue, Olsburg, Onaga, Wheaton, and St. George reported that they do levy
property taxes, but do not use any preferential tax districts or special assessments for purposes of
mitigation activities.
Spending
The fourth major power that has been delegated from the Kansas General Assembly to local governments
is the power to make expenditures in the public interest. Hazard mitigation principles can be made a
routine part of all spending decisions made by the local government, including the adoption of annual
budgets and a Capital Improvement Plan (CIP).
A CIP is a schedule for the provision of municipal or county services over a specified period of time.
Capital programming, by itself, can be used as a growth management technique, with a view to hazard
mitigation. By tentatively committing itself to a timetable for the provision of capital to extend services, a
community can control growth to some extent, especially in areas where the provision of on-site sewage
disposal and water supply are unusually expensive.
In addition to formulating a timetable for the provision of services, a local community can regulate the
extension of and access to services. A CIP that is coordinated with extension and access policies can
provide a significant degree of control over the location and timing of growth. These tools can also
influence the cost of growth. If the CIP is effective in directing growth away from environmentally
sensitive or high hazard areas, for example, it can reduce environmental costs.
Pottawatomie County (unincorporated) and the city of Wamego currently do utilize capital improvement
planning capabilities for growth management. The cities of Westmoreland, St. Marys, Louisville,
Havensville, Olsburg, Onaga, Emmett, Belvue, Wheaton, and St. George reported that they currently do
not utilize capital improvement planning capabilities for growth management.
3.10.3 Program Capability
This part of the capabilities assessment includes the identification and evaluation of existing plans,
policies, practices, programs, or activities that either increase or decrease the community’s vulnerability to
natural hazards. Positive activities, which decrease hazard vulnerability, should be sustained and enhanced
if possible. Negative activities which increase hazard vulnerability should be targeted for re-consideration
and be thoroughly addressed within the Mitigation Strategy for entire Pottawatomie County planning area.
National Flood Insurance Program (NFIP)
The decision on whether to join the NFIP is very important for a jurisdiction (community). There is no
Federal law that requires a jurisdiction to join the program, and participation is voluntary. A benefit of
participation is that the citizens are provided the opportunity to purchase flood insurance to protect
themselves against flood losses. Another consideration is that a jurisdiction that has been identified by
FEMA as being flood-prone and has not joined the NFIP within one year of being notified of being
mapped as flood-prone will be sanctioned.
Page 52 of 252
Jurisdictions that regulate development in floodplains are able to participate in the National Flood
Insurance Program (NFIP). To participate in the NFIP the jurisdicion must adopt and enforce floodplain
management regulations that meet or exceed the minimum requirements of the program.
The jurisdiction must submit an application package that includes the following:
• The jurisdiction must make an Application for Participation in the NFIP (FEMA Form 81-64);
• The jurisdiction must adopt a Resolution of Intent, which indicates an explicit desire to participate in
the NFIP and a committment to recognize flood hazards and carry out the objectives of the program;
• The jurisdiction must adopt and submit Floodplain Management Regulations that exceed the minimum
flood plain management requirements of the NFIP (Title 44 of the Code of Federal Regulations (44
CFR) section 60.3);
• The jurisdiction's floodplain management regulations must be legally enforceable.
Pottawatomie County (unincorporated) adopted floodplain management regulations as part of the
Pottawatomie Unified Development Regulations on January 5, 2009. The resolution applies to all areas
designated as unumbered A Zones, AE, AO, and AH Zones on the existing FEMA Firm Maps dated
February 4, 1998. No development shall be permitted, except through the issuance of a floodplain
development permit through the Board of County Commissioners. The Floodplain Administrator is
responsible for review of all applications to assure that sites are reasonably safe from flooding, and that
the floodplain development permit requirements of the resolution have been satisfied before presentation
to the Commission for final approval. Further floodplain identification and mapping may potentially be
required in the future to update flood maps to determine base flood elevations in the county.
The City of Wamego has floodplain management regulations in Article 4 of Chapter XVI Zoning and
Planning of the Code of the City of Wamego, last amended on February 18, 2003. The article applies to
all lands within the City of Wamego identified as numbered and unnumbered A and AE Zones on FIRMs
(Flood Insurance Rate Maps) dated March 17, 2003 and February 17, 1988.
The City of St Marys passed floodplain regulations on November 3, 2008. The regulations apply to all
lands shown on the FEMA studies and FIRMs dated July 6, 1982, February 17, 1988, and February
1,1980 to be designated within the boundaries of the Floodway or Floodway Fringe Districts within the
corporate limits of the city. Currently, ten (10) residents have flood insurance with coverage of
$1,727,400. St. Marys has had twenty-five (25) insurance claims since 1978 for $11,899.
The City of Onaga passed floodplain regulations on September 3, 2002. The regulations apply to all lands
identified as unnumbered A zones on the FEMA Flood Insurance Rate Mape (FIRM) or the Index Map
dated August 23, 1976 of the Flood Hazard Boundary Map (FHBM) as ammended, and any future
revisions thereto. Currently, zero residents have flood insurance coverage in Onaga.
The City of Belvue participates in the NFIP as NSFHA (No Special Flood Hazard Areas) status.
Therefore, all of Belvue is classified as Zone C. There are no flood insurance maps designating floodplain
areas within the city. Currently, no resident has a flood insurance policy within the city limits. The city is
in the process of obtaining a new FEMA FIRM and drafting floodplain regulations.
St. George passed a Floodplain Management Ordinance in Article IX of the Special Purpose Planning
Ordinance. Currently, five (5) residents have flood insurance with coverage of $616,700. St. George has
had one insurance claim since 1978 for no compensation.
Louisville was mapped on December 2, 1988, but does not participate in the NFIP.
The City of Westmoreland reported that the city is not mapped and does not currently participate in the
NFIP.
Olsburg has not been mapped and currently does not participate in the NFIP.
Page 53 of 252
Havensville has not been mapped and does not participate in the NFIP.
Wheaton has not been mapped and currently does not participate in the NFIP.
Emmett has not been mapped and does not participate in the NFIP.
Pottawatomie County (unincorporated) and the cities of Wamego, St. Marys, Onaga, St. George, and
Belvue, are committed to continued participation and compliance with the National Flood Insurance
Program (NFIP). Specific Actions that were identified in support of the NFIP are provided in Section 5.2 Mitigation Actions.
Community Rating System Activities (CRS)
Insurance Program (NFIP). In return, the NFIP makes federally backed flood insurance policies available
for properties in the jurisdiction. The Community Rating System (CRS) was implemented in 1990 as a
program for recognizing and encouraging jurisdiction floodplain management activities that exceed the
minimum NFIP standards. There are ten CRS classes. Class 1 requires the most credit points and earns the
largest premium reduction, while Class 10 receives no premium reduction. It is a long process to become
a participating CRS community, taking almost one year from application to acceptance. New CRS
communities are admitted only on October 1 and May 1 of each year.
Pottawatomie County (unincorporated) and the cities of Wamego, Wheaton, Louisville, Havensville,
Belvue, Emmett, Onaga, Westmoreland, Olsburg, St. Marys, and St. George reported that they do not
participate in the CRS.
Recent Hazard Mitigation Efforts
Pottawatomie County has undertaken specific hazard mitigation efforts in the past by implementation of
the following :
Pottawatomie County has established a Local Emergency Planning Committee (LEPC) on June 3, 2004,
to help assist the County Board of Commissioners with planning relevant to hazard mitigation and hazard
response.
September 27, 2006 Pottawatomie County adopted a Standard Operating Guide to assist with crisis risk
communications in times of a public health emergency.
Burn Ban Resolution (No. 2006-84, Oct. 9, 2006)
Comprehensive Land Plan (No. 6-20-94)
Floodplain Management Plan (Oct. 23,1997)
Additionally, the county posts preparedness and protection guidelines on the county website for natural
hazards and includes: winter weather, tornado, earthquake, flood, and fire survival techniques.
The Bioterrorism and Foreign Animal Disease response plans are also posted for citizen review in the
event of an emergency or disaster.
Emergency Operations Plan
Pottawatomie County has developed and adopted an Emergency Operations Plan that pre-determines
actions to be taken by government agencies and private organizations in response to an emergency or
disaster event. This plan was developed according to the requirements of the Kansas Planning Standard
which incorporates federal requirements in place at the time of development. The plan was originally
adopted in 1987 and the LEOP was recently updated to current State and Federal standards on April 14th,
2009. For the most part, the plan describes the county’s capabilities to respond to emergencies and
establishes the responsibilities and procedures for responding effectively to the actual occurrence of a
Page 54 of 252
disaster.
The plan does not specifically address hazard mitigation, but it does identify the specific operations to be
undertaken by the county to protect lives and property immediately before, during and immediately
following an emergency. There are no foreseeable conflicts between this Hazard Mitigation Plan and
Pottawatomie County’s Emergency Operations Plan, primarily because they are each focused on two
separate phases of emergency management (mitigation vs. preparedness and response). The incorporated
cities within Pottawatomie County are not designated as "jurisdictions" as defined by the State of Kansas
and therefore have not developed and adopted an Emergency Operations Plan. The cities rely on the
Pottawatomie County Emergency Operations Plan in the event of an emergency or disaster event.
Comprehensive Land Use Plan
A Comprehensive Land Use Plan is designed with the goal of balancing environmental protection with
economic development in all areas of the jurisdiction. This plan coupled with various other planning
efforts provides resources to local leaders to establish policies to guide the development of the
community. Annexation, expansion, and building projects are generally guided by these documents.
After completing a review of the Pottawatomie County Land Use Plan, it was determined that there may
be hazard mitigation strategies which the county could implement, but, considering this current mitigation
planning effort, there are no foreseeable conflicts with the goals previously established under the plan.
There is, however, a significant opportunity to enhance hazard mitigation objectives for Pottawatomie
County within this Hazard Mitigation Plan – objectives that go beyond the content within the Land Use
Plan.
Pottawatomie County adotped the US Highway 24 Corridor Plan in 2003 to replace the existing 2020
Comprehensive Land Use Plan adopted in June 1994. The new Corridor Managment Plan aims to control
the access, timing, location and rate or growth within a specified area. The corridor plan has been
reviewed for purposes of this Hazard Mitigation Plan, with special attention paid to those portions which
address natural hazard mitigation. The US 24 Corridor Plan was designed to regulate growth in the
designated corridors: (1) Wamego - Louisville; (2) Wamego - Manhattan including St. George; (3) St.
Marys -Emmett; (4) Flush Road; (5) Lake Elbo Road. The purpose of this plan is to unify local
governments and agencies in order to effectively utilize natural and financial resources to address
solutions to vital issues within this corridor and develope a strategy for future growth practices. The US
Highway 24 Corridor Plan does not address power of acquisition. The City of St. George implemented a
Comprehensive Land Use Plan in - October 2009. The City of Wamego implemented a Comprehensive
Land Use Plan - February 3, 2009. The City of St. Marys implemented a Comprehensive Land Use Plan May 30, 1979. The cites of Emmett and Louisville participate in the Highway 24 Corridor Plan. The cities
of Westmoreland, Wheaton, Havensville, Onaga, Belvue, and Olsburg do not have a Comprehensive Land
Use Plan. Pottawatomie County (unincorporated) and the incorporated cities of Belvue, Onaga, St Marys,
St George, and Wamego support the National Flood Insurance Program. Pottawatomie County
(unincorporated) and the incorporated cities supports the use of best management practices
recommendations of the United States Soil Conservation Service.
Floodplain Management Plan
A Floodplain Management Plan (FMP) is a future-oriented approach to planning in flood risk areas. It’s a
pre-disaster planning approach that is required by the Federal Emergency Management Agency (FEMA)
to continue to participate in the National Flood Insurance Program's Community Rating System (CRS).
Page 55 of 252
Pottawatomie County and the cities of Wamego, Westmoreland, Olsburg, Onaga, St. Marys, and St.
George reported that they do not have a Floodplain Management Plans for purposes of the National Flood
Insurance Program's Community Rating System (CRS). However, this Hazard Mitigation Plan is intended
to fulfill the CRS planning requirement for all jurisdictions when it becomes adopted, and will be
maintained as such.
Stormwater Management Plan
The purpose of the Stormwater Management Plan is to comprehensively address how to meet the many
different but related regulations, adopted plans and programs, and policies that affect urban stormwater,
flooding and associated water-dependent resources.
Pottawatomie County (unincorporated) does apply stormwater management provisions through the
Pottawatomie Unified Development Resolutions, adopted in January of 2009 (#2009-1). The City of
Wamego reported that a Storm Water Management Plan was implemented in May, 2009. The City of
Emmett reported that it has implemented a Storm Water Management Plan. The cities of Westmoreland,
Louisville, Wheaton, St. Marys, Havensville, Olsburg, Onaga, Belvue, and St. George reported that they
do not have a stormwater managment plan.
3.10.4 Fiscal Capability
Pottawatomie County has reported that they have limited fiscal capability to implement hazard mitigation
strategies due to the general economic, environment, and budget pressures in the county. For fiscal year
2008, Pottawatomie County’s adopted budgeted expenditures were $17,037,465. The majority of these
funds are obligated to basic county support services, human services and education. Pottawatomie County
receives 48% of its revenues through Ad Valorem taxes with the remaining revenues coming from various
other sources.
It is possible that Pottawatomie County could afford to provide the local match for the existing hazard
mitigation grant programs if the State of Kansas did not do so itself, but considering the current budget
deficits at both the state and local government level in Kansas, combined with the apparent increased
reliance on local accountability by the federal government, this is a significant and growing concern for
Pottawatomie County.
Wamego has reported that they do have the fiscal capability to contribute up to $1,000,000 to implement
or partially fund hazard mitigation strategies. For fiscal year 2010, Wamego's approved budgeted
expenditures were $10,404,949. The majority of these funds are obligated to basic support services and
human services, with 14.65% of the city's revenue obtained through Ad Valorem tax.
Westmoreland has reported that they have limited fiscal capability to implement hazard mitigation
strategies due to the general economic, environment, and budget pressures in the city. For fiscal year
2008, Westmoreland's adopted budgeted expenditures were $988,383. The majority of these funds are
obligated to basic support services and human services. Westmoreland reported that it could provide the
local match for the current hazard mitigation grant program.
Belvue has reported that they have limited fiscal capability to implement hazard mitigation strategies due
to the general economic, environment, and budget pressures in the city. For fiscal year 2008, Belvue's
adopted budgeted expenditures were $214,804. The majority of these funds are obligated to basic support
services and human services. Belvue reported that it could provide the local match for the current hazard
mitigation grant program.
St. George has reported that they have limited fiscal capability to implement hazard mitigation strategies
due to the general economic, environment, and budget pressures in the city. For fiscal year 2008, St.
George's adopted budgeted expenditures were $524,677. The majority of these funds are obligated to
basic support services and human services. St. George reported that it could not provide the local match
for the current hazard mitigation grant program.
Page 56 of 252
St. Marys has reported that they have limited fiscal capability to implement hazard mitigation strategies
due to the general economic, environment, and budget pressures in the city. For fiscal year 2008, St.
Marys' adopted budgeted expenditures were $5,089,011. The majority of these funds are obligated to
basic support services and human services. St. Marys reported that it could probably provide the local
match for the current hazard mitigation grant program.
Olsburg has reported that they have limited fiscal capability to implement hazard mitigation strategies due
to the general economic, environment, and budget pressures in the city. For fiscal year 2008, Olsburg's
services and human services. Olsburg reported that it could not provide the local match for the current
hazard mitigation grant program.
Emmett reported that they have limited fiscal capability to implement hazard mitigation strategies due to
the general economic, environment, and budget pressures in the city. For fiscal year 2008, Emmett's
services and human services. Emmett estimates that it could not provide the local match for the current
hazard mitigation grant program.
Onaga reported for the fiscal year 2008 adopted budgeted expenditures of $1,148,912. Onaga does have
limited fiscal capabilities to implement hazard mitigation strategies due to beneral economic,
environmental, and budget pressures in the city, but reported that it could provide the local match for the
current hazard mitigation grant program.
Louisville has reported that they have limited fiscal capability to implement hazard mitigation strategies
due to the general economic, environment, and budget pressures in the city. For fiscal year 2008,
Louisville's adopted budgeted expenditures were $44,806. The majority of these funds are obligated to
basic support services and human services. Louisville reported that it could not provide the local match
Havensville has reported that they have limited fiscal capability to implement hazard mitigation strategies
Havensville's adopted budgeted expenditures were $214,256. The majority of these funds are obligated to
basic support services and human services. Havensville reported that it could not provide the local match
Wheaton has reported that they have limited fiscal capability to implement hazard mitigation strategies
Wheaton's adopted budgeted expenditures were $23,000. The majority of these funds are obligated to
basic support services and human services. Wheaton reported that it could not provide the local match for
the current hazard mitigation grant program.
USD 320 is funded through local taxation. Pottawatomie County is responsible for property tax valuation
and collection in support of operation of the public school system based on public education levy. Taxes
are paid to the state then re-distributed back to the county's school districts based on State formula. These
funds generally maintain buildings, provide funds for capital projects, and also include paying salaries,
purchasing textbooks and supplies. USD 320's total budgeted expenditures for 2008 were $22,428,283.
USD 320 reported that it could possibly afford to provide the local match for the existing hazard
mitigation grant programs through bond issues depending on the size of the project.
purchasing textbooks and supplies. USD 323's total budgeted expenditures for 2008-2009 were

384 reported that it could afford to provide the local match for the existing hazard mitigation grant
programs.
Small Impoverished Community Criteria
Under the Disaster Mitigation Act of 2000, FEMA has made special accommodations for "small and
impoverished communities", who will be eligible for a 90% Federal share, 10% non-Federal cost split for
projects funded through the Pre-Disaster Mitigation Grant Program. The community must meet all of the
following criteria:
• Must be a community of 3,000 or fewer individuals that is identified by the state as a rural community,
and is not a remote area within the corporate boundaries of a larger city;
• Must be economically disadvantaged, with residents having an average per capita annual income not
exceeding 80 percent of the national per capita income, based on best available data;
• Must have a local unemployment rate that exceeds by one percentage point or more the most recently
reported, average yearly national unemployment rate;
• Must meet any other factors as determined by the state/Indian tribe/territory in which the community is
located.
Each jurisdiction should consider potential eligibility under this criteria when developing project grant
applications and funding alternatives.
3.10.5 Political Willpower
Many Pottawatomie County residents are becoming more knowledgeable about the potential hazards that
their jurisdiction faces, and in recent years, they have become more familiar with the practices and
principles of mitigation. The county participation in the National Flood Insurance Program, along with the
adoption of Unified Development Resolutions, the Highway 24 Corridor Plan, and other mitigation
ordinances, in addition to steps taken to update emergency operations programs in the county provide
some insight into the communities desire to comply with mitigation policy and procedure. It is strongly
Page 58 of 252
believed that such tangible changes within the community have created a greater sense of awareness
among local residents, and that hazard mitigation is a concept that they are beginning to readily accept and
support.
Because of this fact, coupled with Pottawatomie County’s history with natural disasters, it is expected that
the current and future political climates are favorable for supporting and advancing future hazard
mitigation strategies.

4.0 Risk Assessment
This risk assessment identifies the natural hazards affecting Pottawatomie County. It provides information
on the history and severity of hazards, evaluates the possible effects, identifies vulnerable populations and
assets (buildings, critical facilities and essential infrastructure), and estimates potential losses that might
occur. This risk assessment process identifies the most critical problems and issues--identified as high and
moderate--that require mitigation actions. In summary, the assessment identifies the hazards, assigns a
likelihood value, evaluates vulnerability, and then calculates an overall risk index value.
The goal of risk analysis is to formulate an assessment of the probability of occurrence for a hazardous
event in tandem with its anticipated severity. Probability or likelihood of occurrence is expressed in terms
of events over time. Occurrence probability is determined from actual historical data when available.
Otherwise, it may be described in relative terms (negligible, low, moderate, and high). Severity is
expressed in relative terms of damage, injury, and overall residual impact resulting from the event.
Severity is determined from utilizing established rating systems (e.g., National Fire Protection Association
(NFPA) Material Factors, Fujita Scale, Mercalli/Richter Scale, etc.) or may be derived from subjective
criteria based on justifiable assumptions. Worst-case scenarios can be assumed. Elaborate quantitative
release probabilities are generally not required. Risk analysis should focus on creating reasonable
estimates based on the best available data. Primary components include:
• Probability that a release will occur and any unusual environmental conditions, such as flood plain
areas, seismic activity, or potential for simultaneous occurrence of emergency incidents (e.g., flooding
or fire hazards associated with the release of hazardous materials).
• Classification of potential harm to humans (acute, delayed, chronic) and identification of high-risk
groups.
• Classification of potential harm and damage to commercial livestock (when applicable).
• Classification of potential damage to property (temporary, repairable, permanent).
• Classification of potential damage to the environment (recoverable, permanent).
4.1 Identification of Hazards
Multihazard Requirement §201.6(c)(2)(i): [The risk assessment shall include a] description of the type … of all
natural hazards that can affect the jurisdiction.
State Hazards Review
When considering the hazards identified for Pottawatomie County, the State Mitigation Plan was
referenced as a comparison to the identified county hazards. The hazards identified on the State list were
compared/eliminated based on the county-specific hazard analysis.

The state, county, and local plans do not address the State Listed Hazards in Table 4.1 (2) because they do
not exist or threaten the jurisdictions of Kansas. As an example, the topography of Kansas does not
contain mountainous areas which would support the possibility of avalanche; the county is not adjacent to
a coastline.
TABLE 4.1 (2) NON-PROFILED HAZARDS
TABLE 4.1 (2) NON-PROFILED HAZARDS
*Thunderstorm
Avalanche
Coastal Erosion
Coastal Storm
Hurricane
Tsunami
Volcano
*NOTE: Thunderstorm, as a specific event, is not included in this analysis. Thunderstorms are common
occurrences in Pottawatomie County, but are considered low-risk due to their typical weak intensity.
However, this plan does address the more significant and severe effects of thunderstorms (i.e., severe
thunderstorms can include lightning, hail, flood, and tornadoes, which can co-exist with microbursts) as
stand-alone events in this report.
The jurisdictions comprising this plan have chosen to use the 58 years of data available from NOAA’s
National Weather Service (NWS) in order to identify hazards which have had an impact on a local basis.
The advantage to using this database is that it provides location, extent, and probability for documented
and reported events over the 58 year period. The intent is to compare the hazards to the State Hazard list
and then to apply extent and probability in order to prioritize and rank the hazards.
It should be recognized that the NOAA data for the overall multi-jurisdictional area did not document or
report events for the following state listed hazards. The MPC found no local data to document or report on
these hazards; estimated the overall probability as low; or found that they are covered by other
circumstances or plans as noted below. Consequently, the MPC eliminated them as hazards to address in
the plan.
Agricultural Infestation - The MPC found no jurisdiction specific data to support this hazard as a High or
Moderate type. Generally, local infestations are mitigated by the land owner with limited other assistance.
Livestock related infestation would be covered by the County Foreign Animal Disease Plan.
Soil Erosion and Dust – No documented or reported significant events. Related crop or agro damage was
found to be covered by private insurance.
Expansive soils; Land Subsidence - The MPC found no jurisdiction specific data to support this hazard as
a High or Moderate type. Geology would not indicate a significant issue.
Extreme Temperatures – NOAA data for Excessive Heat has been matched to this hazard and is addressed
in the plan as such.
Drought - NOAA data for drought has been matched to this hazard and is addressed in the plan as such.
Fog - NOAA data for fog has been matched to this hazard and is addressed in the plan as such.
Flood, Flash Flood, Heavy Rain, and Urban Flood are classified as Flood for planning purposes.
Page 61 of 252
Hazardous Materials – The MPC found that this potential hazard is addressed by the County Local
Emergency Operations Plan (LEOP) and other requirements of SARA Title III. Preparation, mitigation,
and funding is addressed by the LEOP.
Lightning - NOAA data for TSTM (Thunderstorm) Wind has been matched to this hazard and is
addressed in the plan as such.
Major Disease Outbreak – The MPC found that this potential hazard is addressed by the County Public
Health Plan (CPHP) and its continuing development. Preparation, mitigation, and funding is addressed by
the CPHP.
Radiological - No documented or reported significant events. No reported facilities in the jurisdictions
with reportable quantities per SARA Title III. This hazard would also be addressed as part of the Local
Emergency Operations plan when identified.
Windstorm - NOAA data for High Wind has been matched to this hazard and is addressed in the plan as
such.
NOAA also documents and reports several other potential hazards in a more detailed fashion. This would
include: TSTM Wind, High Wind, Blizzard, Heavy Snow, and Winter Storm. After reviewing the NOAA
definitions, the MPC elected to address TSTM Wind and High Wind as TSTM Wind, and to address
Winter Storm, Ice Storm, Blizzard, Extreme Windchill, and Heavy Snow as Winter Storm. Where
provided, the table data for all is listed for informational purposes and future planning consideration.
Earthquake - Although many micro-earthquakes occur at various small scale faults, most of the seismic
activity that occurs in Kansas is attributed to two major geologic structures; the Central Kansas Uplift, and
the Nemaha Ridge/Humboldt Fault Zone (NRHF), and to a lesser extent, the Mid-continent rift zone.
Nemaha Ridge is a buried granite mountain range that trends northeast and extends from near Omaha,
Nebraska to Oklahoma City, Oklahoma. Formed about 300 million years ago during the Pennsylvanian
period, this structure separates the Salina and Sedgwick basins from the Forest City and Cherokee basins
of eastern Kansas.
Based on the following two paragraph summary of the U.S. Army Corps of Engineers Study - Damage
Potential / Tuttle Creek Reservoir study and the listing of historical events, the MPC catagorizes
Earthquake as Negligible.
To structures such as major dams and power plants, even a low-probability earthquake has to be taken
seriously. Lying only 12 miles from the Humboldt Fault, the Tuttle Creek Dam has become a subject of
study by seismologists at the U.S. Army Corps of Engineers. They contend that based on the design of the
dam the smallest earthquake that could potentially cause significant damage is a magnitude 5.7
earthquake. With a predicted probability of occurrence of about once in 1,800 years, it should not cause
total failure of the dam. A magnitude 6.6 earthquake however, “would cause the sand deposits under the
dam to liquefy, or turn to quicksand, and lose their ability to support the dam. This, in turn, would allow
the base of the dam to spread and the top to drop, and cracking would significantly reduce the ability of
the dam to hold water.” The predicted probability of occurrence for this size of event is about once in
10,000 years. (KGS 2001)
As noted in the probability of occurrence for the two hypothetical quake scenarios utilized in the Tuttle
Creek Reservoir investigation, The USACE considers the likelihood of a significant earthquake as
negligible (Preston Johnson, 2008 / Professor James S. Aber, Emporia State University).
Please note the following with regard to the following Tables and Figures:
• Magnitude classifications for tornadoes are based upon the accepted intensity scales for each. Other
hazards are classified by their maximum potential severity or as otherwise deemed appropriate.
Page 62 of 252
• The following tables illustrate the results from applying the risk-rating algorithm for analysis and
hazard profile, and form the basis of risk for each type of potential hazard event identified in
• The hazards Dam/Levee, Terrorism/Agri-Terrorism/Civil Disorder, and Utility Failure are State
mandated hazards which must be considered and addressed in all Kansas plans. Table 4.1 (3) indicates
no documented or reported events in the NOAA database. Any documentation of events outside this
database will be discussed in the Hazard Profile. Since the MPC has elected to address only hazards
ranked as High and Moderate, these hazards were given a Risk Rating of 1, which would cause them to
rank in the Moderate category. This will also incorporate the hazards into the review process over the
next five years.

4.2 Risk and Vulnerability
Due to the limitations of capabilities, discussed in other sections, and the overall desire to focus on the key
hazards, the participating jurisdictions chose to rank or prioritize the local hazards. As most jurisdictions
are just beginning the overall mitigation planning process and are cognizant of the need to focus the
Page 63 of 252
available time and effort, the following methods were used to produce the overall priority rankings of the
local hazards. Each year the jurisdictions will review and update its available resources and evaluate the
benefit of including low or negligible hazards.
The availability of detailed, consistent, and reliable data provided by the National Climatic Data Center
(NCDC) allows the calculation of relative risk values for natural weather events. A standardized set of
data is routinely tracked by the NCDC for an established inventory of individual natural hazard types.
NCDC has tracked this type of data for over 58 years, and has set the standard for developing likelihood
and severity for damage events. For this reason, a similar algorithm has been established for other hazards
identified in this plan to formulate a hazard risk rating to normalize risk comparison.
The columns in Table 4.1 (3) record information regarding the frequency, and impact (or strength) of the
particular natural event and include the following:
•
•
•
•
•
•
Likelihood (occurrences over time)
Magnitude (in terms of Fujita Scale, hail diameter, or wind speed)
Deaths
Injuries
Property damage
Crop damage
This information provides the basis for establishing likelihood and severity ratings. The rate of occurrence
is established from the data record time interval and the number of events recorded. These primary factors
of severity and likelihood of occurrence provide the basis for calculating hazard risk.
As published in Hazard Identification and Risk Assessment by Geoff Wells (copyright 1996), a
reasonable determination of risk may be obtained through the combined calculation of measured severity
and the likelihood of occurrence for any particular hazard. Risk Rating can then be defined in the
following equation:
Risk Rating (RR) = Severity Index (Si) X Likelihood of Occurrence (Li)
Risk Ratings were calculated for individual weather events and are presented in column 10 of Table 4.1
(3) – Pottawatomie County Risk Rating. This table combines the categories of likelihood and vulnerability
to obtain the risk rating for each potential hazard.
The following table and figures have been completed to provide a summary of hazard events analysis, and
present a broad profile of each hazard relative to one another. Determining the risk rating establishes a
numeric ranking for each hazard relative to one another. The risk-rating process is then simplified into the
risk index, Table 4.3 (1), which leads to conclusions on hazard risk and forms a basis for prioritizing
future mitigation efforts as outlined in this plan.
The columns for Table 4.1 (3) are defined per the following two Figures. These assigned values are taken
directly from the NWS data and allow for a direct calculation of overall risk by providing severity and
likelihood.
The column labeled Severity Rating, or M, in Table 4.1 (3) is defined by Figure 4.2 (1) which is itself
titled Event Magnitude Ratings (M) for natural events. Each event has been assigned a severity rating for
magnitude based on the probable impact of the event. Gradational rating systems were employed to allow
a more precise determination of magnitude. Where possible, gradational rating systems were developed
from widely accepted rating systems currently in use. Gradational rating systems have been established
for the following natural events: hail, wind, seismic, and wildfire. Magnitudes for hail events were
developed from an assessment of the NCDC severe weather event database and are based on hailstone
diameter. Magnitudes for tornado and high wind events are drawn directly from the Fujita Scale and are
based on wind speed ranges. Magnitudes for seismic events were assigned relative to the Modified
Page 64 of 252
Mercali Index rating system which establishes earthquake magnitudes relative to damage thresholds.
Magnitudes for wildfire events were generated through an assessment of the State Fire Marshall Office
database and are based on financial loss in terms of appraised value per acre burned.
The columns labeled (D) Death, (I) Injury, (Pd) Property Damage, and (Cd) Crop Damage in Table 4.1 (3)
are defined by Figure 4.2 (2) Severity Ratings. All of these categories are common parameters to natural
events and are typically captured when recording and reporting natural event data. Death and injury
indices are measured in terms of population impacted. Property and crop damage indices are measured in
terms of financial loss (dollars). The gradational rating system for population and assets severity indices
was established through evaluation of severity categories published in the Geoff Wells text, Hazard
Identification and Risk Assessment (1996). These values are assigned based on the parameters listed in
the body of the matrix which is in the last column.
Table 4.1 (3) uses all this data to calculate the Likelihood, total a Severity value, and then uses the
formula of Likelihood X Severity = Risk to produce a risk or vulnerability value for each local hazard.
The data in images 4.2 (1) and 4. 2 (2) are either NOAA ratings or calculated ratings.

4.2.1 Likelihood of Occurrence
The data record time interval is determined from the difference between the beginning and ending dates of
the record inventory. For natural hazard data, the data record time varies from approximately 15 years to
58 years. (EFM updates its overall NCDC database every three years.) Table 4.1(3) provides the data
record time in the “#Years” column. The total number of individual weather events can be extracted from
the inventory of data. Given this information, likelihood of occurrence (in units of events/year) for a
particular weather event is calculated as the quotient of the number of weather events as the numerator
and data record time interval as the denominator. Similar data is extrapolated for other hazards.
Likelihood of Occurrence (Li) = Number of Events / data record time interval (years).
Risk ratings for other types of hazards may be determined on the availability of historical frequency data
and a subjective assessment of predicted severity.
E-Fm updates the national weather data on a three-year basis. In some cases the reported number of
hazard events in E-Fm’s Risk Rating Table may vary from data found on the NCDC Storm Event
Reporting Tool.
The NCDC also reports certain types of storm events, such as blizzards, in regions or “zones”, and as a
consequence does not attribute certain hazard events to individual counties. To increase the accuracy of
individual county event reporting, E-Fm’s algorithm adjusts for the zone factor and attributes the events to
each county that is included in the zone.
4.2.2 Severity Rating
Severity rating tables were established for each of the standard data categories tracked by the NCDC and
assigned a lower limit of 0.5 and an upper limit of 5.0. From these tables, severity ratings were derived for
each of the possible natural events. The severity ratings are identified as follows:
•
•
•
•
•
Magnitude Sr (M)
Death Sr (D)
Injury Sr (I)
Property damage Sr (Pd)
Crop damage Sr (Cd)
The Severity Index (Si) for a particular event (Column 9 in Table 4.1 (3) is calculated as the sum of the
five individual Severity ratings (Sr)).
4.2.3 Other Likelihood and Severity Values
Kansas Wildfire Risk Rating Procedure
The State Fire Marshal’s Office has required counties to formally report wild/rangeland fires since 1997.
A summary of the database, by county, was provided to E-Fm for use in developing a severity and risk
Page 66 of 252
rating for this hazard event. Relatively little historical data was available, making a comparative analysis
to other hazard events difficult. It was necessary to develop an events/time baseline for comparison of
wildfire to other reported hazard events. To obtain the desired results, the consultant normalized existing
data to more closely resemble reporting patterns found in the NCDC database, and expands the time
element of the wildfire reporting data. Our target was to predict data for the time period of approximately
1950 to 2002.
The Plan Author compiled a state-wide database from all reported NCDC weather events since 1950 to
develop the annual reporting events for the State of Kansas. This data was then sorted by year and
analyzed utilizing exponential smoothing of the data. This is an accepted methodology to produce a
smoothed Time Series. Comparatively, in single moving averages, the past observations are weighted
equally, exponential smoothing assigns exponentially decreasing weights as the observations get older. In
other words, recent observations are given relatively more weight in forecasting than the older
observations. Based on the review of weather data, the assumption that wildfire reporting would follow a
similar pattern was adopted.
In the case of moving averages, the weights assigned to the observations are the same and are equal to
1/N. In exponential smoothing, however, there are one or more smoothing parameters to be determined
(or estimated) and these choices determine the weights assigned to the observations. For this analysis,
0.25 was used as the damping factor to eliminate unwanted cyclical and irregular variations. The result
was a representative curve which could be used to predict past reporting of wildfire data.
The seven years of county data was averaged and used as the maximum value on the curve. The
exponential curve was applied using this maximum value and individual yearly data were produced. This
process provided a longer reporting period which effectively lowered the overall likelihood value and
placed the risk rating for wildfires in a more usable range.
For more information regarding risk and vulnerability analysis reference Pottawatomie County’s Hazard
Analysis.
Seismic Risk Rating
Advances in technology, coupled with numerous federal, state and local research institutions have
increased our awareness and understanding of seismic events through monitoring and tracking seismic
activity across the country. There are two generally accepted methods for measuring the strength of a
seismic event. The Richter scale is the most common method used by seismologists to quantify the
“magnitude” of an earthquake. The modified Mercalli Scale (MMI) provides a semi-quantitative method
for expressing earthquake “intensity” and is based on the type and amount of damage caused by the
earthquake and the observations of people within the area where the activity is felt. By comparative
conversion of the Richter and Mercalli measurements, in conjunction with past-recorded events and the
seismic zone rating map of the United States, it possible to develop relative probability of occurrence for
seismic events in tandem with its anticipated severity.
An objective assessment of this information will be made to determine the best available data for risk
calculation. Likelihood of Occurrence will be measured in units of events/year. In cases where local or
regional data is unavailable, state averages for occurrence frequencies will be used. Risk ratings for other
hazards may be based on the availability of historical frequency data and a subjective assessment of
predicted severity. Seismic event (earthquake) likelihood is based on statewide recorded events across a
database timeframe of ~110 years.
4.3 Risk and Vulnerability Index
Multihazard Requirement §201.6(c)(2)(ii): [The risk assessment shall include a] description of the jurisdiction’s
vulnerability to the hazards described in paragraph (c)(2)(i) of this section. This description shall include an
overall summary of each hazard and its impact on the community.
Page 67 of 252
In order to accomplish the final relative priority ranking, a statistical analysis of the Risk Ranking values
was undertaken for a representative number of values from across the state. The analysis was used to
produce quadrants which could be used to identify the highest ranking through the lowest ranking hazards.
The graphing of the data produced the normal curve of values and the three interior break points (changes
in the slope of the curve) were identified. The analysis suggested the following values as dividing lines to
form four ranking quadrants. The jurisdictions agreed to use the following definitions based on the Risk
Ranking value analysis.
•
•
•
•
High Risk = 5.0 or greater
Moderate Risk = 1.00 to 5.0
Low Risk = 0.76 - 0.99
Negligible Risk = less than 0.75
Risk Index: reference the methodology section for greater detail in development of hazard risk-ratings for
the identified hazards. For ease of interpretation in this format the Hazard Risk Index Ratings are based on
either:
•
•
•
•
1 = High Risk
2 = Moderate Risk
3 = Low Risk
4 = Negligible

4.3.1 Pottawatomie County Hazards Index
In many cases, the hazards common to the State Plan and Pottawatomie County's hazard assessment were
determined to be low or negligible risk, and as a consequence, are not included as primary planning risks
for the county. The focus of this mitigation plan is natural hazards, and also includes State-required
planning hazards for Terrorism/Agri-terrorism/Civil Disorder, and Dams/Levees planning requirements.
Pottawatomie County, Kansas, is faced with the following prioritized hazards and potential hazardous
events. For the purposes of this planning event, Pottawatomie County has elected to only address the
hazards classified as “High” and "Moderate”, based on severity and frequency of occurrence. The results

4.3.2 Conclusions on Hazard Risk
Based upon the completion of the hazard identification and analysis, hazards of significance have been
classified as high or moderate. A majority of these hazards impact the entire county and are considered
multijurisdictional hazards. FEMA and the State of Kansas has further delineated Utility Failure,
Terrorism/Agri-Terrorism/Civil Disorder, Dam/Levee, and Wildfire as hazards that vary across the
planning area, and will be addressed as such in this plan. These classifications will be used as a basis for
concentrating and prioritizing current and future mitigation efforts.
A summary of hazards is provided in Table 4.3.2 (1) for jurisdictions included in the Pottawatomie
County Plan.

4.4 Moderate / High Hazard Profiles
Multihazard Requirement §201.6(c)(2)(i): [The risk assessment shall include a] description of the … location
and extent of all natural hazards that can affect the jurisdiction. The plan shall include information on previous
occurrences of hazard events and on the probability of future hazard events.
A descriptive analysis follows with the general hazard profile, history and jurisdiction impacts, location
and extents, and probability of occurrence for the significant hazards identified in Pottawatomie County.
Historical records are used to help identify the level of risk, with the methodological assumption that the
data sources cited are reliable and accurate.
Due to its unique geographical setting, Pottawatomie County is vulnerable to a wide array of natural and
manmade phenomena that pose a threat to life and property. This multi-jurisdictional mitigation plan is
developed to address only the high and moderate hazards classified in the hazard/risk assessment. Other
Page 70 of 252
hazards identified during the assessment which were classified as low or negligible were statistically
eliminated from priority planning based on the probability (likelihood) and vulnerability (severity) of
these hazard events.

Some hazards common to the State Plan and Pottawatomie County's hazard assessment were determined
to be low or negligible risk, and as a consequence, are not included as primary planning risks for the
county. The focus of this mitigation plan is natural hazards, and also includes FEMA and State required
planning hazards for Flood, Terrorism/Agri-terrorism/Civil Disorder, and Dam/Levee.
In some instances, local jurisdictions have identified unique hazards not identified at the county level.
These hazards are profiled by the specific jurisdiction.

Utility Failure
Hazard Profile
The concept of “cascading hazards” relates to the propensity of a primary or source hazard to spawn or
generate additional hazards, commonly known as cascading hazards. On the first level, primary hazards
can bring about secondary hazards. Subsequently, secondary hazards may escalate into tertiary hazards
and so forth. The extent of cascading hazards is potentially limitless.
Power failure can be defined as any interruption or loss of electrical service due to disruption of power
transmission caused by natural hazards (weather events), accident, sabotage, or equipment failure. A
significant power failure is defined as power incident which would require the involvement of the local
and/or state emergency management organizations to coordinate provision of food, water, heating, shelter,
etc. Typically, a power outage is a cascading effect of a larger natural hazard.
In terms of electric power, the cities of Wamego and St. Marys provide service to their citizens. Bluestem
Electric Cooperative, Westar, and Nemaha-Marshall Electric Cooperative provide electric service to
Onaga, Westmoreland, St.George, Emmet, Belvue, Louisville, Olsburg, Havensville, Wheaton, and the
rural portions of Pottawatomie County.
This disaster deals with the loss of electric power supplied by the local utility providers for potential loss
of electricity during severe storms, or ice accumulation on lines causing large areas of power outages
within Pottawatomie County.
Additionally, this disaster could also cover very high levels of power usage during a severe heat wave that
causes a utility company to resort to a series of rolling blackouts in which certain areas would be
purposely shut off from power during peak usage times for four to five hours or more.
The failure of larger main electric feeder lines can also result in large area power outages.
History and Jurisdiction Impacts
The State of Kansas is part of one of four interdependent power grids (Eastern Interconnection) spanning
the United States and Quebec, Canada. The electric power grid is a highly interconnected and dynamic
system of over 3,000 public and private utilities and rural cooperatives. These utilities have incorporated a
wide variety of information and telecommunications systems to automate the control of electric power
generation, transmission, and distribution. Due to this interconnectivity, small outages can sometimes
create problems on a large scale.
In recent years, regional electric power grid system failures in the western and northeastern United States
have demonstrated that similar failures could happen in Kansas. This vulnerability is most appropriately
addressed on a multi-state regional or national basis. Another recent concern that could affect the
functioning of utilities and infrastructure is cybersecurity.
For the most part, it appears severe winter storms create the most widespread threat to electrical
transmission failure in Pottawatomie County. Recent winter storms causing power failure are discussed
below.
December 6, 1994, a winter storm affected a six county area, including Pottawatomie County, with
prolonged freezing rain. It was reported that 30,000 people were without power. There was $100,000 in
property damage reported and no injuries reported for this event.
January 17, 1996, a winter storm affected 23 counties, including Pottawatomie County. The storm
produced five inches of snow and winds up to 60 mph. Homes with power outage were common and
water pipes froze in some buildings. There was no damages and eight injuries reportedfor this event.
January 3, 2004, two to five inches of snow fell in parts of Pottawatomie County resulting in $20,000 in
Page 72 of 252
reported property damage. There was reported power outage due to downed power lines. No injuries were
reported for this event.
Location and Extents
Electrical power outages/blackouts or loss of transmission lines are hard to quantify, and are generally
unpredictable in nature. Additionally, power outages could have a county-wide impact.
Probability of Future Occurrences
Statistical data for analysis at the county level was not readily available from local sources, so
Pottawatomie County relied on the data provided in the State of Kansas Mitigation Plan, and past severe
weather events to quantify this hazard. While utility failures occur annually, this hazard’s probability is
calculated to be a high risk based on the winter storm probability of 4.2 events per year.

Drought
Hazard Profile
Drought can be defined as a period of abnormally dry weather sufficiently long enough to cause serious
effects on agriculture and other activities in the affected area.
Categories of Drought
Droughts can be grouped into four basic categories based on the severity and impact of the occurrence.
These are meteorological, hydrological, agricultural, and socioeconomic. Since they are largely
categorized by impact, it is possible, if not likely that these conditions could exist simultaneously.
Meteorological drought is defined solely on the basis of the degree of dryness, expressed as a relationship
between actual precipitation and the expected average or normal amount, based on monthly, seasonal, or
annual time scales. A meteorological drought description considers only the physical at tributes of the
event and not the impact on social or environmental systems.
The remaining three categories consider both the meteorology of the event as well as the various impacts.
Hydrological drought is associated with the effects of periods of precipitation (including snowfall) short
falls on surface or subsurface water supply (e.g., streamflow, reservoir and lake levels, ground water) .
The frequency and severity of hydrological drought is often defined on a watershed or river basin scale.
Although all droughts originate from a deficiency of precipitation, hydrologists are more concerned with
how this deficiency plays out through the hydrologic system. Hydrological droughts are usually out of
phase with, or lag behind the occurrence of meteorological and agricultural droughts. I t takes longer for
precipitation deficiencies to show up in components of the hydrological system such as soil moisture,
streamflow, and ground water and reservoir levels. As a result, these impacts are also out of phase with
impacts in other economic sectors. For example, a precipitation deficiency may result in a rapid depletion
of soil moisture that is almost immediately discernible to agriculturalists, but the impact of this deficiency
on lake and stream levels may not affect fisheries or recreational uses for many months.
Agricultural drought links various characteristics of meteorological (or hydrological) drought to
agricultural impacts. This view of drought focuses on precipitation shortages, differences between actual
and potential evapo-transpiration, soil water deficits, and reduced groundwater or reservoir levels, and
their effects on agricultural product ion. Plant water demand depends on prevailing weather conditions,
biological characteristics of the specific plant, its stage of growth, and the physical and biological
properties of the soil. The definition of agricultural drought accounts for the variable susceptibility of
crops during different stages of crop development, from emergence to maturity.
Socioeconomic definitions of drought associate the supply and demand of economic goods with elements
of meteorological, hydrological, and agricultural drought . The supply of many economic goods, such as
water, forage, food grains, fish, and hydroelectric power, depends on weather. Because of the natural
variability of climate, water supply is ample in some years but unable to meet human and environmental
needs in other years. Socioeconomic drought occurs when the demand for an economic good exceeds
supply as a result of a weather- related short fall in water supply.
There were four periods of drought reported for Pottawatomie County from 1993 to 2008. Pottawatomie
County falls in an area that experiences arrid and dry periods that can become a drought. Drought and
periods of extreme summer heat can have a negative impact on the economy by affecting agriculture. The
2007 Kansas Department of Agriculture Farm Facts indicates 830 farms, ranking 24th in the state, and
468,000 acres of land in farms, ranking 47th in the state. Pottawatomie County ranks 62nd in farm value
of crops harvested ($44,704,600), and 39th in the value of cattle and milk production in the state
($30,181,400). Crops consist of wheat (245,000 bushels), corn (4,418,000 bushels), and sorghum
Page 74 of 252
(411,800 bushels). Cattle and calves inventory in January 2008 was 75,100 head valued at $65,350,000.
Data for hogs, sheep, and poultry were not available at the county level. A summary of three droughts
reported for Pottawatomie County are provided as follows:
November 1, 1999: extreme dryness and above normal warmth persisted throughout most of the month for
the twenty-three county area. The excessive dryness affected many crops such as winter wheat and also
contributed to a number of reported wildfires. There were no reported property damages, crop damages,
deaths or injuries for this event.
September 1, 2002: The drought conditions that started in July continued through September. Many crops
and pasturelands over the area were greatly affected. Farm ponds were void of ample water for cattle and
crops were either plowed up or made into fodder for farm animals. No actual crop damage figures were
available but estimates for all of northeast Kansas were likely to exceed 25 million dollars. Additionally,
there was no reported property damages, deaths, or injuries.
November 1, 2002: After a brief respite from an unusually wet October the dry weather of this past
Summer returned in November. Although temperatures averaged near normal over the twenty-three
county area, precipitation amounts averaged 1.5 to 2 inches below normal. There was no reported property
damage, crop damage, deaths, or injuries for this event.
There is no distinct geographic boundary to Drought, and it can occur in every area of the county equally.
While Pottawatomie County buildings, critical facilities, infrastructure and lifelines, and hazardous
materials facilities may be exposed to extreme weather related conditions brought on by a period of
drought and could potentially be impacted, it is expected that the greatest exposure to this hazard is on the
population, agriculture, and livestock of Pottawatomie County. Hazard workshops are considered a viable
option to educate the local residents and will be considered in the future. See Section 5.2 Mitigation
Actions.
The probability of a drought depends on summer weather patterns that pass through the state. The
likelihood of future events is estimated to remain the same as currently calculated. Pottawatomie County
can expect drought conditions once every 3.75 years (0.27 probability/year).
Although we extract data and probability of occurrence from historical information, the risk of drought
appears to be a random event.

Excessive Heat
Hazard Profile
Severe, excessive summer heat is characterized by a combination of a very high temperatures and
exceptionally humid conditions. When persisting over a period of time, it is called a heat wave. Many
areas of the country, especially the Rio Grande Border Region, are susceptible to heat waves.
The major human risks associated with severe summer heat include heatstroke, heat exhaustion, heat
syncope, and heat cramps. Most at risk are outdoor laborers, the elderly, children, and people in poor
physical health. The effects of severe summer heat are always more pronounced in urbanized areas than in
rural areas. Within urbanized areas, the problem is exacerbated by what is known as the heat island effect,
in which the concrete and metal infrastructure absorbs radiant heat energy from the sun during the day and
radiates that heat energy during the night. This cyclical process essentially “traps” the heat in the
urbanized area and makes it as much as 10 degrees warmer than the surrounding hinterland.
Severe summer heat is an invisible killer. Although a heat wave does not happen with the spectacle of
other hazards such as tornadoes and floods, the National Center for Environmental Health reports that,
from 1979 to 1999, excessive heat exposure caused 8,015 deaths in the United States. In other words,
during this period, more people in the U.S. died from severe summer heat than from hurricanes, lightning,
tornadoes, floods and earthquakes combined.
During the summer months, the State of Kansas is frequently affected by severe heat hazards. Persistent
domes of high pressure establish themselves, which set up hot and dry conditions. This high pressure
prevents other weather features such as cool fronts or rain events from moving into the area and providing
necessary relief. Daily high temperatures range into the upper 90’s and low 100’s. When combined with
moderate to high relative humidity levels, the heat index moves into dangerous levels, and a heat index of
105 degrees is considered the level where many people begin to experience extreme discomfort or
physical distress.
July 23, 1997: temperatures in the upper 90s to near 105 combined to produce heat indices as high as 110
degrees. High temperatures in the town of Onaga ranged between 100 and 105 each day from the 23rd to
27th. There were no reported fatalities or injuries for this event.
September 1, 2000: the excessive heat of August continued into the first 3 days of September, and
temperatures soared well above 100 degrees in many locations. There were no damages or injuries
July 16, 2006: afternoon high temperatures across a twenty-three county area rose above 100 degrees at
many locations during the 5 day span. Heat Index readings climbed to 105 to 115 degrees at some
locations. Railroad tracks near St. Mary's (Pottawatomie County) buckled in the heat on the 17th, and 30
cars derailed. Three people were reportd needing medical treatment for heat-hyperthermia, however,
several newspapers indicated "several" or "a handful" of people were treated for heat related illnesses at
area hospitals.
There is no distinct geographic boundary to Excessive Heat. While Pottawatomie County buildings,
critical facilities, infrastructure and lifeline facilities may be exposed to Excessive Heat, it is expected that
the greatest exposure to this hazard is on the population of Pottawatomie County rather than impacting
physical county assets.
The likelihood or future probability of a significant occurrence of excessive summer heat in the county is
Page 76 of 252
considered to remain the same as calculated. Pottawatomie County can expect an excessive heat event
every 1.37 years (0.73 chance/year).
Although we extract data and probability of occurrence from historical data, the risk of excessive heat
appears to be random.

Terrorism / AT / CD
Hazard Profile
Vector-based hazards have become an "emerging" threat to the state, local governments, and its citizens.
Insects, infectious diseases, and naturally-occurring and manmade biological agents can pose a direct or
indirect hazard to humans, livestock, and the state's economy. The State of Kansas has made this hazard a
priority for the State and local government planning requirements.
Numerous definitions for “vector” have been proposed, and vary with the nature and focus of the specific
discipline of research such as epidemiology, public health, mathematics, and most recently - Emergency
Management. This section will focus primarily on Emergency Management’s role with infectious Foreign
Animal Disease (FAD), biological agents, and/or by-products utilized to create weapons of mass
destruction (WMD), which could otherwise require a response from emergency management departments.
Other forms of communicable disease and biological/chemical agents are causes for concern. However,
authority and response to these potential health issues resides with agencies and disciplines such as the
Food and Drug Administration (FDA), Center for Disease Control (CDC), and Public Health
Departments, and therefore will not be mentioned in this section. Emergency Management roles and
responsibilities will likely change with time requiring refinement and expansion of response for this
discipline.
Potential threats to U.S. agriculture and livestock can arise from a variety of pathogens and causative
agents. Terrorist attacks against agricultural assets might be tempting, due to the perceived relative ease of
attack, the plausible deniability toward accusations, and the limited number of plant seed varieties in use.
Highly infectious naturally-occurring plant and animal pathogens exist outside the U.S. borders, and some
agents are readily transported, inadvertently or intentionally, with little risk of detection.
Nature has already shown how easy it might be for a sophisticated, technically-informed state, group, or
individual to attack crops and livestock by introducing a new parasite, predator, or disease. There are a
host of “rusts” and “smuts” that can attack grain crops, as evidenced by past naturally-occurring events in
the U.S.
The list of threats (exotic diseases) to livestock is substantial. They include, but are not limited to, animal
disease, plant disease, Foot and Mouth Disease (FMD), vesicular stomatitis, Bovine Spongiform
Encephalopathy (BSE), rinderpest, gibberella, African swine fever, highly pathogenic avian influenza,
Rift Valley fever, lumpy skin disease, blue tongue, sheep and goat pox, swine vesicular disease,
contagious bovine pleuropneumonia, Newcastle disease, African horse sickness, and classical swine fever.
Animal health officials define an exotic or FAD as an important transmissible livestock or poultry disease
believed to be absent from the United States and its territories, and capable of generating potential
significant health or economic impact. FMD, anthrax, BSE, rinderpest, and swine fever are potential ways
to attack livestock.
Although terrorist-type activities/incidences are a relatively new type of threat to Kansas, these types of
activities, if present, are not readily available or reported to the public. Pottawatomie County has not
documented terrorist activities in their county, but the State of Kansas has made this hazard a priority for
the State and local government planning requirements. Federal and state officials understand local-level
resources will be the first to respond to any emergency situation and have acknowledged the fact that local
planning and preparation, even if resources are exhausted quickly, will play a major role in mitigating a
terrorist attack or outbreak of an exotic disease. Research suggests the best approach is to broaden the
prevention, response and recovery spectrum for emergency operations planning to include all hazards,
with the understanding that limited resources and funding at the local level will require quick evaluation
Page 78 of 252
of an event in order to efficiently respond to the emergency and to obtain state and federal assistance in a
timely fashion.
The Department of Homeland Security required all states and local jurisdictions to update their terrorist
security databases in 2003. Pottawatomie County provided a self-assessment of risk and vulnerability
during this planning event. Additionally, the State of Kansas required all jurisdictions to plan for potential
bio-terrorism events, and develop local foreign animal disease plans. As a result, Pottawatomie County
has selected this hazard category as a priority for inclusion in the county's Mitigation Plan, as the role of
emergency management will be fine tuned for prevention, response, and recovery activities involving a
FAD and/or bio-terrorist event to provide the resource support needed to effectively and efficiently deal
with the disease onset and lifespan.
The entire county is considered equally susceptible to Terrorism and FAD.
Although initial detection of this type of event is considered uncontrollable, it is highly possible an act of
terrorism (domestic or other) could occur at any time given the right circumstances. However, the
probability of future occurrence is reduced due to proactive preventative action on the part of Federal,
State and local authories. This proactive approach to preparation and prevention will help reduce the
potential for losses to property and life as a result of terrorist or FAD outbreaks.
The risks associated with Terrorism appear to be a random event with a low risk probability, but is
included in the plan as a state-mandated planning hazard.

Fog
Hazard Profile
Fog is a cloud at ground level, water droplets suspended in the air at the earth’s surface. Fog forms when
the air cannot hold all the moisture it contains. This happens when air is cooled to its dew point, which is
the temperature at which air is holding as much moisture as it can. When air reaches its dew point it
condenses into very small particles, forming the tiny water droplets that comprise fog.
The intensity and duration of fog varies with the location and type of fog - from early morning ground fog
that burns off easily to prolonged valley fog that can last for days. Generally, strong winds tend to prevent
fog formation. The following list summarizes several possibilities for the format ion, intensity, and
duration of fog in the Midwest.
Ground Fog is associated with clear nights, stable air (winds less than 5 mph), and a small- temperature
dew point range. It forms when heat radiates away from the ground, cooling the ground and surface air.
When air cools to its dew point, fog forms, usually a layer of less than 100-200 feet . It is common in
many areas of the United States and generally burns off by morning sun.
Advection Fog is associated with horizontal wind, warm, humid air, and winter temperatures. It forms
when wind pushes warm humid air over the cold ground or water, where it cools to the dew point and
forms fog. Advection fog can cover wide areas of the central U.S. in winter. During the winter this is
common when snow covers much of the Midwest. The snow cools the bottom portion of the moist air
mass often resulting in condensation. This type of fog can be widespread, covering very large areas.
Evaporation Fog is associated with bodies of water. It forms as cold air blows over warmer water, causing
the water to evaporate into the cold air, increasing the humidity to the dew point . Vapor condenses,
forming a layer of fog 1 to 2 feet thick over the water. It can form over ponds and streams on fall days.
Precipitation Fog: is associated with warmer rain and cooler air. It forms when rain evaporates, and the
added vapor increases the air to its dew point. The vapor then condenses into fog. Precipitation fog forms
on cool, rainy days.
Areas of Pottawatomie County along the Kansas River and its tributaries' valleys as well as other
low-lying areas can be at greater risk for fog under certain meteorological conditions. However, no part of
the county is free of the possibility of experiencing fog. There have been eight fog events reported for
Pottawatomie County over the past 15 years.
January 10, 2003, dense morning fog reduced visibility to a quarter mile or less across a fifteen county
area. There were no reported injuries or damages for this event.
July 1, 2005, widespread dense fog reduced visibility to less than a quarter mile, creating very hazardous
driving conditions, from 2:00 AM to 8:00 AM across a nineteen county area. There were no reported
injuries or damages for this event.
December 25, 2005, dense fog on Christmas evening compounded the already dangerous high traffic.
However, no major accidents, injuries, or damages were reported for this event.
The entire county is considered equally susceptible to periods of fog.
Although we can estimate probability of occurrence from historical information, Pottawatomie County
can expect one fog event every 1.9 years (0.53 chance/year).

Hail
Hazard Profile
Hail can be produced from many different storm types. Typically hail is a cascading hazard of a
thunderstorm event. It is estimated that damage from hail approaches $1 billion in the U.S. annually. U.S.
agriculture is typically the most affected by such hail storms. Hail causes severe crop damage and even a
minor storm with relatively small-size hailstones can have a devastating effect. As well, damage to
vehicles, roofs (residential/commercial), and landscaping are the other things most commonly damaged by
hail National Weather Service (NWS), and National Oceanic and Atmospheric Administration (NOAA).
Early in the developmental stages of a hailstorm, ice crystals form within a low-pressure front due to the
rapid rising of warm air into the upper atmosphere and the subsequent cooling of the air mass. Frozen
droplets gradually accumulate on the ice crystals until, having developed sufficient weight, they fall as
precipitation—as balls or irregularly shaped masses of ice greater than 0.75 in. (1.91 cm) in diameter. The
size of hailstones is a direct function of the size and severity of the storm. High velocity updraft winds are
required to keep hail in suspension in thunderclouds. The strength of the updraft is a function of the
intensity of heating at the Earth’s surface. Higher temperature gradients relative to elevation above the
surface result in increased suspension time and hailstone size. Figure 1 displays the annual frequency of
hailstorms in the State of Kansas.
Figure 1 - FEMA Hailstorm Map of Kansas
There were 206 reported hail events in the 51-year NCDC database time frame for Pottawatomie County.
No deaths or injuries were attributed to any of the reported events. The National Climatic Data Center
(NCDC) reported $66,000 in accumulative property damage and $5,000 in crop damages for
Page 82 of 252
The largest event reported in the county was a 4.0-inch hail event which occurred June 29, 1998, three
miles southwest of Olsburg. There were no damages or injuries reported for this event.
September 21,1993, two-inch hail and high winds were reported seven miles west of Blaine to three miles
north of St. Marys. The storm caused $50,000 in property damage, and $5,000 in crop damage. No
injuries were reported for this event.
June 10,1998 - Wamego, there was 1.75 inch hail that caused $15,000 of property damage, including
broken windows on houses and cars. No crop damage or injuries were reported for this event.
The entire Pottawatomie County area is equally susceptible to damage from hail in association with severe
thunderstorms.
The probability of a hailstorm event depends on certain atmospheric and climatic changes. The likelihood
of future events is estimated to remain the same as currently calculated. Pottawatomie County can expect
an average of 4.04 hail events a year, with average annual damages of $1,392.
Although we can estimate probability of occurrence from historical information, the risk of hail appears to
be a random event.
Page 83 of 252
Tornado
Hazard Profile
A tornado is a violent windstorm characterized by a twisting, funnel-shaped cloud extending to the
ground. It is most often generated by a thunderstorm and produced when cool, dry air intersects and
overrides a layer of warm, moist air forcing the warm air to rise rapidly. The damage from a tornado is a
result of the high wind velocity and wind-blown debris, although they are commonly accompanied by
large hail as well. The most violent tornadoes have rotating winds of 250 miles per hour or more and are
capable of causing extreme destruction, including uprooting trees and well-made structures, and turning
normally harmless objects into deadly missiles.
Most tornadoes are just a few dozen yards wide and touch down only briefly, but highly destructive
tornadoes may carve out a path over a mile wide and several miles long. The destruction caused by
tornadoes may range from light to inconceivable depending on the intensity, size and duration of the
storm. Typically, tornadoes cause the greatest damages to structures of light construction, such as
residential homes, and are quite localized in impact.
Each year an average of 800-1,000 tornadoes are reported nationwide and they are more likely to occur
during the spring and early summer months of March through June. Tornadoes can occur at any time of
day but are mostly likely to form in late afternoons and early evenings.
The magnitude or severity of a tornado was originally categorized using the Fujita Scale or Pearson Fujita
Scale (introduced in 1971). The Fujita Scale categorizes tornadoes from F0 (Gale) to F5 (Inconceivable)
based on wind speed. It is used to rate the intensity of a tornado by examining the damage caused by the
tornado after it has passed over a manmade structure.
Other scales have been developed to measure wind and tornado intensity including the Beaufort Wind
Scales (B-Scales) and Britain’s Tornado Storm and Research Organization (TORRO) Scale (T-Scale).
However, the Beaufort and TORRO scales are generally not used to identify the severity or intensity of a
tornado or wind event in the United States.
However, the early version of the Fugita scale recently become obsolete, due to many weaknesses in the
system that have resulted in misuse and/or misunderstanding of the scale. It was replaced on February 1,
2007, by the Enhanced Fujita Scale, or EF Scale (Figure 1). This new scale continues to rate the strength
of tornadoes in the United States based on the damage caused. The scale has the same basic design as the
original Fujita Scale (six categories from 0 to 5 representing increasing degrees of damage). It was revised
to reflect better examinations of tornado damage surveys to align wind speeds more closely with
associated storm damage. As with the Fujita Scale, though, each damage level is associated with a wind
speed. The Enhanced Fujita Scale is a damage scale and the wind speeds associated with the damage
listed remain unverified and little more than educated guesses. The EF Scale improved on the old scale on
many counts. It accounts for different degrees of damage that occur with different types of natural and
man-made structures based on how they are designed, as well as providing a much better estimate for
wind speed, including setting no upper limit for wind speed at the strongest--EF5--level. (NOAA-SPC,
2007)
Page 84 of 252
Figure 1 - Enhanced Fujita Scale
There have been 3,454 confirmed tornadoes in Kansas during the period 1950-2008, resulting in 228
deaths and 2,699 injuries, with total damages estimated at $2,602,507,870. Typically, Kansas’s tornadoes
can be severe when compared to other parts of the country. Compared with other states, Kansas ranks
number four in the country for frequency of tornadoes, third for number of deaths, third for injuries, and
third for cost of damages.
According to the National Climatic Data Center, there have been 26 confirmed tornadoes in Pottawatomie
County since 1951 that were reported to have resulted in five injuries and approximately $2.388 million in
property and crop damages. The strongest tornado recorded in Pottawatomie County had a magnitude of
F3. This event occurred May 31,1978. To view the entire record of Pottawatomie County tornado events
reference Figure 3.
May 31, 1978, a tornado with a magnitude of F3 was reported in Pottawatomie County that caused
$250,000 in property damage. The tornado was reported to be 1,300 yards in width and on the ground for
19 miles. No other damages or injuries were reported for this event.
May 6, 1993, a tornado with a magnitude of F1 was reported near Wheaton that caused $500,000 in
property and $50,000 in crop damage. The tornado was reported to be 100 yards in width and on the
ground for 4 miles. There were no deaths or injuries reported for this event.
June 4, 2005, a tornado with a magnitude of F1 was reported in the southwest part of Pottawatomie
County that caused $250,000 in property damage. The tornado was reported to be 100 yards in width and
on the ground for one mile. No deaths or injuries were reported for this event.
The Wind Zones in the State of Kansas (Source: FEMA) depicted in Figure 2 provides an overview of the
potential wind strength potential. Pottawatomie County lies within Zone IV, with wind speeds capable of
Page 85 of 252
up to 250 miles per hour based on past historical data.
Figure 2 - FEMA Wind Zones Map
The damage from a tornado is a result of high wind velocity and wind-blown debris. The potential damage
resulting from a tornado is directly correlated to the strength of the particular tornado and is qualified
utilizing the Enhanced Fujita Scale. The EF Scale assigns numerical values based on wind speeds and
categorizes tornadoes from EF0 through EF5. The Enhanced Fujita Scale is shown in Figure 1.
The entire planning area is equally susceptible to damage from tornadoes.
The likelihood of future events is estimated to remain the same as currently calculated. Pottawatomie
County can expect a tornado once every 2.2 years (0.456 chance/year), with average annual damages of
$41,984 a year.

TSTM Wind
Hazard Profile
High winds are generally the result of severe thunderstorms. Straight-line winds, which in extreme cases
have the potential to exceed 100 miles per hour, are responsible for most thunderstorm wind damage. One
type of straight-line wind, the microburst, can cause damage equivalent to a strong tornado and can be
extremely dangerous to aviation. Thunderstorms are also capable of producing tornadoes and heavy rain
that can lead to flash flooding.
Severe thunderstorms are defined by the National Weather Service as storms that have wind speeds of 58
miles per hour or higher, produce hail at least three-quarters of an inch in diameter, or produces tornadoes.
Thunderstorms simply require moisture to form clouds and rain, coupled with an unstable mass of warm
air that can rise rapidly. Thunderstorms affect relatively small areas when compared with hurricanes and
winter storms, as the average storm is 15-miles in diameter and lasts an average of 30 minutes. Nearly
1,800 thunderstorms are occurring at any moment around the world. However, of the estimated 100,000
thunderstorms that occur each year in the United States, only about 10 percent are classified as severe.
Thunderstorms are most likely to happen in the spring and summer months and during the afternoon and
evening hours, but can occur year-round and at all hours.
Despite their small size, all thunderstorms are dangerous and capable of threatening life and property in
localized areas. Every thunderstorm produces lightning, which results from the buildup and discharge of
electrical energy between positively and negatively charged areas. Each year, lightning is responsible for
an average of 93 deaths (more than tornadoes), 300 injuries, and several hundred million dollars in
damage to property and forests across the United States.
Severe thunderstorms and high wind events are very common in Kansas, and cause a significant amount
of property and crop damage annually.
According to the National Climatic Data Center, there were a total of 146 reported thunderstorm/high
wind events reported in Pottawatomie County during the period of 1957 to 2008, causing three injuries,
$9,746,000 in property damage, and $508,000 in crop damage. Damages recorded included downed trees
and damaged roofs and structures (these events do not include tornadoes, as this hazard is discussed
separately). Some examples are as follows:
June 14, 1985, two people were injured in Pottawatomie County attributed to a thunderstorm that reported
a magnitude of 61 knots. There were no damages or deaths reported for this event.
July 1, 1994, Pottawatomie County reported winds of 99 mph at the Jeffrey Power Plant near Emmett that
caused widespread damage across the entire county. Numerous trees, roofs, windows and power lines
were damaged or destroyed. Power was out in many areas for more than 48 hours. At the Jeffrey Power
Plant, 33 empty rail cars were blown from off the track along with damage to coal loading machinery and
buildings. The plant had to briefly shut down. Damage to the power plant was estimated at $2 to $2.5
million, with total property losses to the county of $4 to $5 million. Crop damage was reported at
$500,000, with no injuires reported.
On July 20, 2003, high winds knocked down power poles in St. George. Property damage was reported at
$25,000, with no injuries attributed to this event.
The entire planning area is equally susceptible to damage from thunderstorm high wind.
Page 88 of 252
The probability of a thunderstorm event depends on certain atmospheric and climatic changes. The
likelihood of future events is estimated to remain the same as currently calculated. Pottawatomie County
can expect approximately 2.86 high wind events a year, with average annual damages of $201,058.
Although we can extract data and probability of occurrence from historical information, the risk of
TSTM/high wind appears to be a random event.

Winter Storm
Hazard Profile
Winter storms can produce an array of hazardous weather conditions, including heavy snow, freezing rain
and ice pellets, ice storms, high winds, and extreme cold. Severe winter storms are usually fueled by
strong temperature gradients and an active upper-level cold jet stream. Winter storms can paralyze a
community by shutting down normal day-to-day operations, as accumulating snow and ice result in
downed trees, power outages and blocked or hazardous transportation routes. Heavy snow can also lead to
the collapse of weak roofs or unstable structures. Frequently the loss of electric power means loss of heat
for residents, which poses a significant threat to human life, particularly the elderly.
The level of impact severe winter weather will have upon a community greatly depends on its ability to
manage and control the effects, such as the rapid mobilization of snow removal equipment. Severe winter
weather is a frequent occurrence in Kansas, and can reach blizzard proportions under the right weather
conditions. Many Kansas counties are small, and the costs to acquire and maintain the necessary resources
to combat winter storm effects is expensive, hence, many small communities are not prepared for such
events.
Severe winter storms are typically associated with cold climates; but it is not uncommon for the State of
Kansas to experience significant and even disastrous winter weather events. Since 1993, 38 deaths and 98
injuries have been attributed to snow and ice events throughout the state, along with an estimated
$81,900,000 in property damage. In most instances, these impacts are determined by weather patterns and
cannot be readily identified to particular regions of the state.
Pottawatomie County averages 18.9 inches of snow per year and experiences severe winter storms on
occasion, with 63 winter storm events reported between 1993-2008. Three examples are provided as
follows:
January 29, 2002, a winter storm that included freezing rain and snow enveloped Pottawatomie County.
There was $8,000,000 in property damage and no injuries reported for this event.
March 4, 2003, in Pottawatomie County, a winter storm produced freezing drizzle and one to three inches
of snow. The roads became very slick and hazardous because of driving conditions. One death in a traffic
accident was reported four miles north of Westmoreland. There was no reported property damage and
eight injuries attributed to this event.
January 3, 2004, two to five inches of snow fell in parts of Pottawatomie County resulting in $20,000 in
property damage. No crop damage or injuries were reported for this event.
The entire county is equally susceptible to damage from severe winter storms.
The probability of a severe winter storm event depends on winter weather patterns that pass through the
state. The likelihood of future events is estimated to remain the same as currently calculated.
Pottawatomie County can expect 4.2 winter storms per year, with average annual damages of $240,066.
Although we can extract data and probability of occurrence from historical information, the risk of winter
storm appears to be a random event.

Flood - Pottawatomie (UnInc.)
Hazard Profile
Flooding is the most frequent and costly natural hazard in the United States. Floods are generally the
result of excessive precipitation, and can be classified under two categories: flash floods, the product of
heavy localized precipitation in a short time period over a given location; and general floods, caused by
precipitation over a longer time period and over a given river basin. The severity of a flooding event is
determined by a combination of stream and river basin topography and physiography, precipitation and
weather patterns, recent soil moisture conditions and the degree of vegetative clearing.
Flash flooding events usually occur within minutes or hours of heavy amounts of rainfall, from a dam or
levee failure, or from a sudden release of water held by an ice jam. Most flash flooding is caused by
slow-moving thunderstorms in a local area or by heavy rains associated with hurricanes and tropical
storms. Although flash flooding occurs often along mountain streams, it is also common in urbanized
areas where much of the ground is covered by impervious surfaces.
General floods are usually longer-term events and may last for several days. The primary types of general
flooding include riverine flooding, coastal flooding, and urban flooding. Riverine flooding is a function of
excessive precipitation levels and water runoff volumes within the watershed of a stream or river. Coastal
flooding is typically a result of storm surge, wind-driven waves, and heavy rainfall produced by
hurricanes, tropical storms, nor’easters and other large coastal storms. Urban flooding occurs where
man-made development has obstructed the natural flow of water and/or decreased the ability of natural
groundcover to absorb and retain surface water runoff.
Periodic flooding of lands adjacent to rivers, streams and shorelines is a natural and inevitable occurrence
that can be expected to take place based upon established recurrence intervals. The recurrence interval of
a flood is defined as the average time interval, in years, expected between a flood event of a particular
magnitude and an equal or larger flood. Flood magnitude increases with increasing recurrence interval.
A "floodplain" is the lowland area adjacent to a river, lake or ocean. Floodplains are designated by the
frequency of the flood that is large enough to cover them. For example, the 10-year floodplain will likely
be covered once every 10-years, and the 100-year floodplain covered once every 100-years.
Flood frequencies, such as the "100-year flood," are determined by plotting a graph of the size of all
known floods for an area and determining how often floods of a particular size occur. Another way of
expressing the flood frequency is the chance of occurrence in a given year, which is the percentage of the
probability of flooding each year. For example, the 100-year flood has a 1% chance of occurring in any
given year.
According to the National Climatic Data Center, there were a total of 25 reported flood events in
Pottawatomie County from 1993 to 2008.
June 4, 2005, St. Marys reported a flood that produced over six inches of rain causing high water to flow
across several area roads. Property damage was estimated at $100,000. No crop damage, loss of life, or
injuries were reported for Pottawatomie County.
May 6, 2007, Onaga reported a flood that caused $10,000 in property damage. No injuries were attributed
to the flooding. Pottawatomie County qualified for FEMA funds as a result of this event.
July 20, 2007, St. George reported a thunderstorm that dropped five-inches of rain, causing $70,000 in
property damage and no injuries for this event.
Page 91 of 252
A review of the FEMA FIRM for Pottawatomie County indicates the areas most susceptible to flooding
occur along the low-lying areas of the Kansas and Big Blue rivers and their tributaries that cris-cross the
county. Although there were reported instances of rural flooding, these areas tend to be sparsely
populated.
The likelihood of future events is estimated to remain the same as calculated. Pottawatomie County can
expect 1.67 flood events a year, with average annual damages of $240,066. Although flooding in the rural
areas of the county is considered to be low impact, it will become more of a concern as the county
continues to grow in population.

Wildfire - Pottawatomie (UnInc.)
Hazard Profile
A wildfire is an undesirable, uncontrolled burning of grasslands, brush or woodlands. According to the
National Weather Service, more than 100,000 wildfires occur in the United States each year. About 90%
of these wildfires are started by humans (i.e., campfires, debris burning, smoking, etc.); the other 10% are
started by lightning.
The potential for wildfire depends upon surface fuel characteristics, weather conditions, recent climate
conditions, topography, and fire behavior. Fuels are anything that can and will burn, and are the
combustible materials that sustain a wildfire. Typically, this is the most prevalent vegetation in a given
area. Weather is one of the most significant factors in determining the severity of wildfires. The intensity
of fires and the rate with which they spread is directly related to the wind speed, temperature and relative
humidity. Climatic conditions such as long-term drought also play a major role in the number and
intensity of wildfires, and topography is important because the slope and shape of the terrain can change
the rate of speed at which fire travels.
There are four major types of wildfires. Ground fires burn in natural litter, duff, roots or sometimes high
organic soils. Once started they are very difficult to control, and some ground fires may even rekindle
after being extinguished. Surface fires burn in grasses and low shrubs (up to 4’ tall) or in the lower
branches of trees. They have the potential to spread rapidly, and the ease of their control depends upon the
fuel involved. Crown fires burn in the tops of trees, and the ease of their control depends greatly upon
wind conditions. Spotting fires occur when burning embers are thrown ahead of the main fire, and can be
produced by crown fires as well as wind and topographic conditions. Once spotting begins, the fire will be
very difficult to control.
Wildfires can cause considerable damage and loss of life especially in areas where there is an interface
between wild or range land and urban development. The topography and wind velocity of Pottawatomie
County also influences the spread of wildfires, and the county has multiple fuel sources and is prone to
drought and thunderstorms; therefore, wildfires are a risk for Pottawatomie County.
The NCDC database collects wildfire data for federally-owned land, but does not track private property;
consequently, the Kansas Fire Marshal’s office tracks fire data for private property owners in Kansas.
Collection of data began in 1997. Current information is provided in summary form only and reflects
reported fires on an annual basis by county.
Wildfire in the State of Kansas is better defined as rangeland fire. This type of fire generally originates as
a surface fire and can spread quickly across large areas. When wildfire does occur in Pottawatomie
County, it is also very rare that a home or business is lost, with most damage is limited to field crops.
Wildfire is most common in the spring when brush is still brown and dry, and when fields have reached
maturity in the fall months.
The likelihood of future events is estimated to remain the same as currently calculated. Pottawatomie
County can expect an average of 13.15 wildfires a year that damage or destroy a total of 14,232 acres, and
average 2,372 acres burned per year.
Although one can extract data and probability of occurrence from historical data, the risk of Wildfire

Dam / Levee - Pottawatomie (UnInc.)
This discussion includes all dam and levee structures identified in Pottawatomie County and the
participating jurisdictions. Classification and discussions regarding dams and levees was required by
FEMA as part of this plan. Vulnerability for each jurisdiction is discussed in the next section.
Hazard Profile
DAM
A dam failure is defined as an uncontrolled release of the reservoir. The causes of dam failures can be
divided into three groups: dam overtopping, excessive seepage, and structural failure of a component.
Despite efforts to provide sufficient structural integrity and to perform inspection and maintenance,
problems can develop that can lead to failure. While most dams have storage volumes small enough that
failures have little or no repercussions, dams with large storage amounts can cause significant flooding
downstream. Dam planning is a state-mandated hazard for inclusion in this plan.
Dam failures can result from any one or a combination of the following causes:
1. Prolonged periods of rainfall and flooding, which cause most failures;
2. Inadequate spillway capacity, resulting in excess overtopping flows;
3. Internal erosion caused by embankment or foundation leakage or piping;
4. Improper maintenance, including failure to remove trees, repair internal seepage problems, replace lost
material from the cross section of the dam and abutments, or maintain gates, valves, and other operational
components;
5. Improper design, including the use of improper construction materials and construction practices;
6. Negligent operation, including the failure to remove or open gates or valves during high flow periods;
7. Failure of upstream dams on the same waterway;
8. Landslides into reservoirs, which cause surges that result in overtopping;
9. High winds, which can cause significant wave action and result in substantial erosion; and
10. Earthquakes, which typically cause longitudinal cracks at the tops of the embankments, which can
weaken entire structures.
LEVEE
A levee is a man-made structure; usually earthen embankments designed and constructed in accordance
with sound engineering practices to contain, control, or divert the flow of water so as to provide protection
from temporary flooding.
A levee is generally built parallel to a body of water (most often a river) in order to protect lives and
property behind it from some level of flooding (100-year; 300-year; 500-year flood). Some reasons a
levee may fail include:
1. A flood that exceeds the specific flood level for which the levee was designed may “overtop” (water
can go over the top of the levee);
2. Failure to perform required maintenance, the need for which increases with age;
3. Lack of advance planning, resources and timely action to make the levee system ready for a flood
event;
4.Soil failure, erosion, and intrusion of animals.
Page 94 of 252
DAM
The Dam Safety Program is part of the broader Water Structures Program of the Kansas Department of
Agriculture, Division of Water Resources. The Kansas Stream Obstructions Act (K.S.A. 82a-301 through
305a) gives the Chief Engineer, Kansas Department of Agriculture – Division of Water Resources the
exclusive authority to regulate the construction, operation and maintenance of dams in Kansas. The
written consent or permit of the Chief Engineer is required to construct a dam or make changes in any
dam which meets the regulatory criteria.
NOTE: The State does not regulate Federal Reservoirs. In the State of Kansas, Federal Reservoirs are
inspected, maintained and managed by either the U.S. Corps of Engineers or the Bureau of Reclamation.
Emergency Action Plans (EAP) for these reservoirs, although classified, should be available for local
governments upon request. The EAP should include inundation maps in the event of a flooding event, or
an emergency at the facility.
The Chief Engineer has the power and duty to inspect any State-regulated dam. The Chief Engineer may
issue orders requiring correction of deficiencies or removal of the dam. An annual inspection of all dams
found to be unsafe is required until the deficiency is corrected or the dam is removed.
Where a dam condition is so dangerous as to pose an immediate safety threat, the Chief Engineer shall
immediately employ any remedial means considered necessary. The Chief Engineer shall continue in full
charge and control of any such dam until it is considered safe or the emergency prompting the remedial
action has ceased.
Three dam hazard classifications have been established as described in K.A.R. 5-40-9. These classes are:
1. Class A (low hazard) – dams located in rural or agricultural areas where failure may damage farm
buildings, limited agricultural land, or county, township and private roads.
2. Class B (significant hazard) – dams located in predominately rural or agricultural areas where failure
may endanger few lives, damage isolated homes, secondary highways or minor railroads or cause
interruption of use or service of relatively important public utilities.
3. Class C (high hazard) – dams located in areas where failure may cause extensive loss of life, serious
damage to homes, industrial and commercial facilities, important public utilities, main highways or
railroads.
The referenced hazard classes are solely impact-based. It is important to note that a high hazard dam is not
necessarily unsafe. An individual dam’s hazard classification is based upon the potential consequences of
dam failure and does not reflect the physical condition of the dam. Post-construction development in the
area is evaluated for potential to flood due to failure of the dam (breach inundation zone), and may result
in the dam’s reclassification to a higher hazard class than was originally assigned (Reference: Kansas
Water Plan, Small Dam Safety and Rehabilitation, Policy Section, approved by the Kansas Water
Authority November 18, 2005).
The classifications do not use a calculation of “likelihood” since the inspections do not include an
evaluation of “worthiness” or probability of failure. Also, there are no reported dam failures in
Pottawatomie County, which precludes the calculation of an overall county likelihood. Since likelihood
data is not available for potential dam failure, the county has elected to rely on the State classifications to
prioritize, and to plan for High Hazard Class C dams only for this study.
As a general rule, populations, property and environment residing downstream of dams are most
susceptible to damage from dam failure. The Department of Agriculture - Water Resources identified five
(5) dams in Pottawatomie County as High Hazard, and there have been no reports of dam failure or
damage.
Page 95 of 252
LEVEE
The State of Kansas has four statutes that regulate the design and construction of levees. The Statutes
include: 12-635 Flood Protection; Eminent Domain; 14-434 Power to Regulate; 19-3301 Flood Control;
Counties, and 24-816 Within 1st Class Cities. These statutes guide an owner or community through the
process of developing levees within the county, and mandate requirements for reporting and maintenance
of the levee(s).
FEMA is responsible for identifying flood risks in areas behind levees through flood analysis and flood
hazard mapping projects, including updating the nation’s hazard maps through an effort called Flood Map
Modernization (Map Mod). In addition, FEMA also provides criteria to define which protect against the
1-percent-annual-chance flood. FEMA does not examine or analyze structures to determine their
performance in a given flood event. The levee owner must provide documentation to show that a levee
meets current design, operations, and maintenance criteria. FEMA will accredit levees based on a review
of these criteria. Levee owners or communities have a responsibility to provide documentation that a levee
meets the requirements of Title 44 of the Code of Federal Regulations, Section 65.10, as part of a
study/mapping project. Procedure Memorandum 34 (PM 34) allows for the issuance of a deadline to the
community for submitting the required documentation. (Source: FEMA)
FEMA – Region VII reported that their MAP Mod modernization program focuses on levees found on
existing FEMA Flood Maps (FIRMS) prior to update. FEMA is initiating a process to notify owners,
schedule meetings, and provide guidance to owners. The intent is to assist meeting Federal requirements
and accredit identified levees.
As a general rule, populations, property and environment residing within adjacent land areas of levees are
most susceptible to damage from failure or breach of levee systems. There has been no reports or past
incidents regarding levee failure in Pottawatomie County.
DAM
In Pottawatomie County there are 158 known dams included in the State of Kansas, Department of
Agriculture, Division of Water Resources database. The State data includes public and private-owned
dams, as well as Federal Reservoirs, if within the county boundary. The volume of water impounded, and
the density, type, and value of development downstream determine the potential severity and potential
classification of dam/levee failure.
The Department of Water Resources identified five (5) high-hazard dams in Pottawatomie County that
could impact the county in the event of breach or dam failure. These five dams include the following by
Name/Owner:
College Creek FRD No. 2 / City of St. Marys
Jeffery Energy Center Dam No. 1 / Westar Energy
Jeffery Energy Center; Aux Make-Up / Westar Energy
Pottawatomie State Lake No. 1 Dam / Kansas Department of Transportation
Tuttle Creek Reservoir (shared with Riley County) / US Corps of Engineers
The Department of Water Resources stated that owners of the above-mentioned dams have submitted
Emergency Action Plans (EAP) and inundation maps for approval as required by Kansas Statute. The
findings of the EAP's are as follows:
City of St. Marys - College Creek FRD No. 2 was inspected by the Division of Water Resources (DWR)
on June 4, 2009, meeting the three-year inspection requirement until April 30, 2012. St. Marys drafted an
Page 96 of 252
EAP (emergency action plan) for the College Creek FRD No.2, last revised on September 2, 2009.
According to the EAP, in the event of dam failure, thirteen (13) structures and one road in the eastern
portion of St. Marys that would require evacuation in the event of an emergency. A map referencing the
evacuation area, including labeled structures, is provided in Section 4.5.2.
Jeffery Energy Center, Dam No. 1, and the Jeffery Center Aux Make-Up Dam: Westar Energy has noted
that seven residences would require notification for evacuation in the event of a dam emergency with
either of the Western Resource Jeffery Energy Center structures.
Pottawatomie County State Lake No.1; there are two residences located along Deep Hollow Road in the
east inundation area are to be notified and evacuated in the event of an emergency. Additionally, State
Highway 99 traverses the top of the dam and could be lost if dam failure were to occur.
FEDERAL RESERVOIRS within Pottawatomie County
The Department of Water Resources identified one Federal Reservoir within Pottawatomie County that
could potentially have a negative impact on the county in the event of a breach, overtopping, or failure of
the dam. Tuttle Creek Reservoir, operated by the U.S. Army Corps of Engineers, is the most significant
water body in Pottawatomie County, and is formed by a compacted earthfill dam impoundment of the Big
Blue River within the Kansas-Lower Republican River Basin (watershed). Tuttle Dam is shared between
Pottawatomie and Riley counties, and is located 5-miles north of Manhattan (in Riley County). The Big
Blue river is also the "natural" county boundary between these counties. The Lake was completed in 1962
primarily for flood control for downstream flow of water from a 9,600 square mile drainage area. Tuttle
Lake provides flood protection along the Big Blue River downstream from the dam. As part of the
Kansas-Lower Republican River basin system of lakes, Tuttle Dam also contributes to flood protection on
the Missouri and Mississippi rivers. A potential breach or overtopping of the dam could cause significant
flooding in low-lying areas of the Big Blue, Little Blue, Black Vermillion rivers, and Fancy Creek, and
could affect populations as far away as Kansas City, Missouri.
Flood waters from Tuttle Creek Reservoir could potentially affect residential, commercial, and
agricultural areas downstream, with potential life, social, and economic consequences. Low lying areas
along the rivers, creeks and streams would also be impacted. It was reported that the inundation maps for
this Federal Reservoir is classified under the Patriot Act and not available for review or inclusion in this
Plan.
FEDERAL RESERVOIRS Outside Pottawatomie County
Two Federal Reservoirs were identified outside of Pottawatomie County that could potentially have a
negative impact in the event of a breach, overtopping, or failure of the dam.
Milford Dam is located on the Republican River in Geary County, approximately 5 miles northwest of
Junction City, Kansas. Discharge from Milford Lake flows into the Republican River, and eventually into
the Kansas River. Review of the Milford Lake Emergency Action Plan, prepared by the U.S. Army Corps
of Engineers dated January 2000 (updated 2002), indicated that significant portions of Pottawatomie
County in the general vicinity of the Kansas River valley would be inundated with flood waters from
Milford Lake in the event of a flooding incident. The Emergency Action Plan (EAP) indicated the
following: A spillway design flood with dam failure would impact the area of St. George within eight
hours; Wamego within 40-hours; Belvue within 46.6 hours, and St. Marys within 52.5 hours (Arrival
Time).
Lovewell Dam is located in Jewell County on the White Rock Creek 3-miles northwest of Lovewell,
Kansas. The reservoir stores water from White Rock Creek and diversions from the Republican River by
way of the Courtland Canal. The primary purpose of the dam is for irrigation. The dam was constructed in
1955-1957, and consists of earthfill structure. Failure of this dam could cause potential inundation surge
to the Republican river and affect areas of Pottawatomie County downstream.
Page 97 of 252
The Emergency Management department maintains copies of the EAP in the event of an emergency. It
was reported that the inundation maps for these Federal Reservoirs are classified under the Patriot Act and
not available for review or inclusion in this Plan.
LEVEE
In Pottawatomie County there were no levees identified by the MPC, but the Kansas Department of
Agriculture Division of Water Resources identified twenty unique records for levees in the county.
Although levee ownership information was limited the water number structures are as follows: LPT-0002,
LPT-0003, LPT-0004, LPT-0005, LPT-0006, LPT-0007, LPT-0008, LPT-0009, LPT-0010, LPT-0011,
LPT-0012, LPT-0014, LPT-0015, LPT-0018, LPT-0019, LPT-0020, LPT-0022-C, LPT-0023, LPT-0024,
LPT-0056.
KDA identified levees are not geo-located, but rather are located by Section, Township, and Range only.
Levees were placed into a GIS produced county background to view general locations. None were found
to be within, or close proximity to, any of the jurisdictions. Generally, the levees would be labeled as
agricultural levees. The levees were not identified on existing FEMA FIRM maps, nor are they identified
as county levees subject to PM 43.
The City of St. George reported there is one levee within the corporate limits of St. George. A review of
the FIRM (dated February 4, 1998) indicates that this levee does not appear to protect any areas from the
100-year floodplain. The levee is located on the southern boundary of the city, south of the Union Pacific
railroad tracks and north of the Kansas River. The city reported that the levee is an embankment and was
built by the U.S. Army Corps of Engineers and is now owned by the Union Pacific Railroad.
For reasons previously mentioned and uncontrollable by humans, it is highly possible a dam or levee can
fail at any time given the right circumstances. However, the probability of future occurrence is reduced
due to proactive preventative action on the part of KDA-DWR, (and the overall number of sources in
Pottawatomie County). As previously discussed in this section, KDA-DWR provides oversight to
dam/levee repairs, oversees and issues construction permits, enforces safety standards and mandates,
conducts periodic inspections, and provides public information to levee owners, engineers, and the general
public. This proactive approach to managing dam safety in Kansas reduces the number of losses to
property and life as a result of dam failure or near failure. No dam or levee failure events have been
recorded in Pottawatomie County.
Although we can estimate probability of occurence from historical information, the risk of dam or levee
failure occurring and the location of damage appear to be a random event with a low risk probability.

Flood - Belvue
Hazard Profile
given year.
Pottawatomie County between 1993-2008. One of these events was reported for Belvue as follows:
July 16, 2001, Belvue experienced four inches of rain over a short period causing water to overflow U.S.
Highway 24. There were no injuries, fatalities, crop or property damages reported.
Belvue participates in the National Flood Insurance Program, but does not have any flood hazard
boundaries, flood insurance maps, or designated floodplain areas (SHFAs) within the city. According to a
review of the Kansas Dedpartment of Transportation (KDOT) County Road Map, Belvue does not appear
to have any major streams located within the city limits, but is located near the Kansas River and Lost
Creek, which could subject low-lying areas to flooding.
Page 99 of 252
The likelihood of future events is estimated to remain the same as calculated. Belvue can expect 1.67
flood events per year.

Pottawatomie County between 1993 and 2008. One of these events was reported for Louisville as follows:
May 24, 2007, thunderstorms dropped between two to four inches on Louisville, causing flooding from
Rock Creek. There was $50,000 in reported property damage, but no reported fatalities or injuries for this
event.
A review of the City of Louisville Flood Hazard Boundary Map (December 2, 1988) indicated one
primary flood zone, an AE Zone, in Louisville covering most of the corporate limits. Rock Creek, a
tributary of the Kansas River, flows through the city and most of the developed areas. Vulnerability maps
are provided in Section 4.5.2, and actions for flood are located in Section 5.2.

Flood - Onaga
Hazard Profile
given year.
Pottawatomie County between 1993 and 2008. Three of these events were reported for Onaga as follows:
June 28, 1999, flash flooding resulted from heavy rains: a man was rescued from a vehicle that became
stalled in flood waters 5 miles south of Onaga as well as other locations in the county causing extensive
crop damage and flooding several roads and businesses. No injuries, fatalities, or property damage was
reported, but $50,000 in crop damage was reported for this event.
May 11, 2005, flash flooding resulted in up to six inches of rain that flooded fast flowing water across
some roads in the Onaga area. No injuries, fatalities, or crop damage was reported, but $1,000 in property
damage was reported for this event.
May 6, 2007, heavy rains resulted in flash flooding and flooding causing water to overflow some roads in
the Onaga area. No injuries, fatalities, or crop damage was reported, but $10,000 in property damage was
Page 103 of 252
A review of the FEMA Flood Insurance Rating Map (August 13, 1976) noted one primary flood zone in
the city of Onaga. The flood area is designated Zone A and follows Hine Creek across the southern
portion of the city, which appears to have little development, except for one finger that extends north for
several hundred feet through a improved area. The flood zone includes areas on the south side of the
railroad tracks, and does not appear to impact any improved or populated areas. Vulnerability maps are
provided in Section 4.5.2, and actions for flood are found in Section 5.2.
The likelihood of future events is estimated to remain the same as calculated. Onaga can expect 1.67 flood
events per year.

given year.
Pottawatomie County between 1993 and 2008. Two of these events were reported for St. George as
follows:
May 24, 2007, beginning one mile north northeast of St. George, heavy rains caused flooding and flash
flooding. The incident reported damages for several counties including, $200,000 in property damage, but
no crop damage, deaths, or injuries were reported for this event.
July 20, 2007, flooding in St. George resulted in a ruined foundation of a newly constructed home as well
as the closing of Blackjack Road due to high water. There was $70,000 in reported property damage, but
no crop damage, deaths, or injuries were reported for this event.
A review of the FEMA Flood Insurance Rating Map (February 4, 1998) noted two primary flood zones in
Page 105 of 252
the City of St. George. One flood zone is a Zone A and lies in the northwest portion of the city, west of
Jackson Street, following Blackjack Creek to the Union Pacific (UP) railroad tracks where it becomes an
AE Zone. The other primary flood zone is an AE zone south of the UP railroad tracks in proximity to
Blackjack Creek and the Kansas River. Vulnerability maps are provided in Section 4.5.2, and actions for
flood are located in Section 5.2.
The likelihood of future events is estimated to remain the same as calculated. St. George can expect 1.67

Pottawatomie County between 1993 and 2008. Four of these events were reported for St. Marys as
follows:
July 6, 2004, Highway 24 was reported to be covered with water from flash flooding in St. Marys. There
was no reported damages or injuries for this event.
June 4, 2005, flooding one mile north of St. Marys resulted in six inches of fast flowing water across
several roads in the area. There was $100,000 in property damage and no injuries reported for this event.
October 2, 2005, flooding in St. Marys resulted in six inches of fast flowing water across Highway 24.
There was $150,000 in property damage and no injuries reported for this event.
April 26, 2009, one mile west-southwest of St. Marys resulted in flowing water across Highway 24,
rendering it impassable. There was no property damage or injuries were reported for this event.
Page 107 of 252
A review of the FEMA Flood Insurance Rating Map (July 6, 1982) noted three primary flood zones in the
City of St. Marys. The flood zone farthest east is along the east boundary of the corporate limits along
Willard Creek, consisting of zones A3 and A8. The flood zone along the southwest corporate boundaries
of the city runs from Willard Creek to College Creek and is all Zone B. The southeast flood zone follows
College Creek, turning back west in the corporate limits, consists of zones A3, A6, and A0. Reference

given year.
Pottawatomie County between 1993 and 2008. Three flood events were reported for Wamego as follows:
July 2, 2004, heavy rains produced flash flooding and water across several city streets in Wamego. There
was no reported damages or injuries for this event.
May 26, 2007, Wamego reported five inches of rain that caused flooding of over one foot of fast flowing
water across several area roads. The intersection of 99th and Lincoln was reported specifically for flooded
streets. Other damage included garages and basements, as well as washed out railroad tracks. Property
damage was estimated at $150,000, with no reported injuries for this event.
June 12, 2007, Wemego, highways 24 and 99 were reported to be flooded and impassible during the
heavy rainfall. Property damage was estimated at $10,000 with no reported injuries for this event.
Page 109 of 252
A review of the FEMA FIRM (March 17, 2003) noted three flood zone areas in the City of Wamego. The
flood zone along the Kansas River is Zone AE, and runs along the south edge of the corporate limits of
Wamego. Another flood zone is along the east edge of Wamego and follows Cat Creek (a tributary of the
Kansas River), and is a combination of Zones A and AE. The third zone follows East Unnamed Creek (a
tributary of the Kansas River) from the west corporate limits of the city, turning northwest back through
the city and out of the north corporate limits. This flood zone consists of both A and AE zones. Most of
these areas appear to contact developed land.
The likelihood of future events is estimated to remain the same as calculated. Wamego can expect 1.67
4.5 Vulnerability Assessment
Multihazard Requirement §201.6(c)(2)(ii): [The risk assessment shall include a] description of the jurisdiction’s
vulnerability to the hazards described in paragraph (c)(2)(i) of this section. This description shall include an
overall summary of each hazard and its impact on the community.
The vulnerability assessment was completed predominantly through the use of objective hazard and risk
analysis, along with the use of county-provided data and best available information at the time of the
study. It describes the county’s hazard prone locations and provides an inventory of repetitive loss
properties (if applicable) and critical facilities. This portion of the plan also describes current development
trends and implications for Pottawatomie County, and includes maps that were generated specifically to
illustrate jurisdiction vulnerability. Lastly, this section discusses what was learned through the process of
determining the county’s current and future vulnerability to natural hazards, and provides several
conclusions on community vulnerability.
Natural Hazards
Situated in the central portion of the country, Pottawatomie County is located in an area that is prone to
the effects of sudden collision of cold/warm fronts creating winter storms (blizzard, ice, heavy snow, etc.),
and thunderstorms (high wind, hail, tornadoes, heavy rain, lightning, etc.). Areas throughout the county
are vulnerable to the natural hazards identified in Section 4.0, and for the most part, face a uniform level
of risk for each hazard, with the exception of flood, wildfire, and dam/levee failure. This is due to the
nature of the natural weather events that occur in the county. Hail, thunderstorm high winds, winter
storms, lightning, and tornadoes are unpredictable and random in nature. Since the majority of the county
is rural, coupled with its sparse pattern of land development, it does not present areas that are significantly
more vulnerable to property loss than others. The majority of people who live and work in Pottawatomie
County reside in Wamego and St. Marys, but the probability that a jurisdiction would be affected more
often than other areas in the county is considered statistically very low.
Based on historical data, and for purposes of this hazard mitigation plan, Pottawatomie County will assess
the above-referenced natural hazards vulnerability on a countywide planning basis. Flood, dam/levee and
wildfire will be addressed as separate geographic planning areas.
4.5.1 Damage and Vulnerability Overview
Multihazard Requirement §201.6(c)(2)(ii)(A): The plan should describe vulnerability in terms of the types and
numbers of existing and future buildings, infrastructure, and critical facilities located in the identified hazard
area …

Where data failure occurred, subjective data was used to obtain estimated facility/infrastructure costs. The
following tables attempt to assess the potential damage and vulnerability of Pottawatomie County based
on these estimates. Table 4.5.1 (1) was completed to assess the current and future vulnerability of
Pottawatomie County based upon the assessed value of assets within the jurisdiction. The inventory costs
are based on the number and assessed valuation and do not reflect replacement value for other assets such
as land, equipment, fixture, and furniture assets. A breakdown of urban and rural public utilities was not
available, consequently, all utilities are included under the urban category.

It is anticipated that when more data is obtained through development and cataloging of cadastral data,
more accurate replacement cost data will be included in future updates to this Plan.
In addition to being used for general mitigation planning purposes, this vulnerability assessment can be
used by Pottawatomie County as documentation to support the need for mitigation projects that can be
funded through the Federal Hazard Mitigation Grant Program (HMGP), the Pre-Disaster Mitigation
Program (PDM) and/or similar grant programs. The information gathered for public buildings and critical
facilities can also be used when applying for both Federal and State Public Assistance funds which
provide assistance for the repair and mitigation of public facilities and infrastructure following declared
disaster events.

4.5.3 Vulnerability Estimation by Hazard
E-Fm utilized geographic distribution of natural hazards to develop vulnerability estimates, as
recommended by FEMA, for hazards of planning significance. This generally involves assessment of the
event location along with the extent and frequency of damage incurred over time. Natural hazards
identified as multijurisdictional are those hazards that impact the entire geographical area of the county in
a generally random and unpredictable manner.
Natural hazards identified by FEMA, that are considered local hazards for vulnerability assessment,
include: flood, wildfire, and dam/levee failure. These hazards generally create localized damage exposure
so vulnerability is treated as a separate geographical planning area for these hazards.
With limited objective flood related data on structures and populations in flood hazard areas and limited
data on the appraised values of real property by land use, in the overall multijurisdictional areas of
Page 154 of 252
Pottawatomie County, estimates of damage inflicted by various types of natural hazards will be offered in
a tabular format.
The principal resource in developing loss estimates for the county or municipality was provided by the
National Climatic Data Center (NCDC), and best available information relating to populations and the
value of real, commercial, and personal property, by jurisdiction, as obtained from various state and
county sources. The purpose of this information is to show the overall population numbers and property
values that would be subject to natural hazards in the jurisdictions of Pottawatomie County.
The qualitative approach used a two step process. The first step analyzed Severity Table 4.2 (2). NCDC
provides five categories for severity of damage for deaths, personal injury, property damage, and crop
damage. As an example, property damage reported in the database ranges from less than $10,000 to
greater than $100,000,000 per event. The consultant recommended the following for consideration:
• A value of 5 in the Severity table be considered as complete destruction (> $100,000,000);
• Values of 0.5, 1 and 2 be considered as 1% damage (1,000,000/100,000,000 = 1% in a worst case
scenario)
• Value of 3 be considered as greater than 1% and up to 10% damage (10,000,000/100,000,000 = 10% in
a worst case scenario)
• Value of 4 be considered as greater than 10% and up to 50% damage (50,000,000/100,000,000 = 50%
in a worst case scenario)
The MPC accepted this scale based on the fact that it is documented data provided by NCDC records.
Step 2 required each jurisdiction to agree on a final damage percentage considering local observations,
total values in Table 4.5.1 (1), and specific jurisdiction values provided by the Appraisers office and listed
in the vulnerability tables in Section 4. After this consideration, the damage percentage was assigned and
used for calculations. If, by consensus, the jurisdiction chose a percentage outside the proposed ranges,
then an explanation is provided, such as for flood and tornado.
Wildfire related data to structures, crops, and people were provided by the Kansas Fire Marshall's Office.
Data for dam/levee was provided by the Kansas Department of Agriculture (KDA) - Division of Water
Structures, and consists of dam/levee inventories and dam classifications developed by the KDA. The
hazards identified as high and moderate were assessed utilizing available quantatative analysis and/or loss
estimation. Hazards that were researched but provided little data for evaluation were analyzed from a
qualitative perspective.
Page 155 of 252
Flood
Floods are generally a result of slow-moving thunderstorms that deposit large volumes of water over an
extended period of time. Heavy thunderstorm/rain may result in localized areas of flash flooding. This
hazard is addressed separately by geographical area where data is provided by the jurisdiction.
National Flood Insurance Program (NFIP)
The decision on whether to join the NFIP is very important for a jurisdiction (community). There is no
Federal law that requires a jurisdiction to join the program, and participation is voluntary. A benefit of
participation is that the citizens are provided the opportunity to purchase flood insurance to protect
themselves against flood losses. Another consideration is that a jurisdiction that has been identified by
FEMA as being flood-prone and has not joined the NFIP within one year of being notified of being
mapped as flood-prone will be sanctioned.
Insurance Program (NFIP). To participate in the NFIP the jurisdicion must adopt and enforce floodplain
management regulations that meet or exceed the minimum requirements of the program.
The jurisdiction must submit an application package that includes the following:
• The jurisdiction must make an Application for Participation in the NFIP (FEMA Form 81-64);
• The jurisdiction must adopt a Resolution of Intent, which indicates an explicit desire to participate in
the NFIP and a commitment to recognize flood hazards and carry out the objectives of the program;
• The jurisdiction must adopt and submit Floodplain Management Regulations that exceed the minimum
flood plain management requirements of the NFIP (Title 44 of the Code of Federal Regulations (44
CFR) section 60.3);
• The jurisdiction's floodplain management regulations must be legally enforceable.
Pottawatomie County adopted floodplain regulations, outlined in Article X of the Pottawatomie Unified
Development Regulations, and require a floodplain development permit for all proposed construction or
other development, including the placement of manufactured homes in all lands identified as unnumbered
A zones, AE, AO, and AH on the Index Map dated February 4, 1998 of the Flood Insurance Rate Map
(FIRM). Pottawatomie County and the cities of St. George, St. Marys, Belvue, Onaga, and Wamego are
committed to continued participation and compliance with the National Flood Insurance Program (NFIP).
Specific Actions that were identified in support of the NFIP are provided in Section 5.2 - Mitigation
Actions.
Community Rating System Activities (CRS)
Insurance Program (NFIP). In return, the NFIP makes federally backed flood insurance policies available
for properties in the jurisdiction. The Community Rating System (CRS) was implemented in 1990 as a
program for recognizing and encouraging jurisdiction floodplain management activities that exceed the
minimum NFIP standards. There are ten CRS classes. Class 1 requires the most credit points and earns the
largest premium reduction, while Class 10 receives no premium reduction. It is a long process to become
a participating CRS community, taking almost one year from application to acceptance. New CRS
communities are admitted only on October 1 and May 1 of each year.
Pottawatomie County and the incorporated cities do not currently participate in the CRS program.
Repetitive Loss Inventory
The Kansas Department of Emergency Management (KDEM), Mitigation Planning Division, was
contacted regarding “repetitive loss properties” that may exist in Pottawatomie County. KDEM maintains
records obtained from the Federal Emergency Management Agency (FEMA), Region VII, on repetitive
loss properties in the State of Kansas.
Page 156 of 252
Although there are separate definitions for what constitutes a repetitive loss property among various
programs, FEMA generally considers it to be “any property, which the National Flood Insurance Program
has paid two or more flood claims of $1,000 or more in any, given 10-year period since 1978.”

The three referenced repetitive loss properties were listed in the State of Kansas/FEMA database as
residing in both Pottawatomie County and Riley County. The Knox Lane, North 3rd, and Skyway Drive
properties noted above are reported to physically reside in Pottawatomie County, but are incorporated in
the City of Manhattan. The MPC reported that responsibility for these properties belong to the city of
Manhattan and are included in the Riley County Mitigation Plan.
Reference Section 3.10.2 Legal and Regulatory Capability - "Acquisition" for information on other
properties mitigated in Pottawatomie County that were not classified as repetitive loss properties.
Flood inundation areas for Pottawatomie County (unincorporated) and participating (mapped)
communities were determined by use of FEMA boundary maps which were geo-coded using
Manifold.Net, a GIS application. The GIS application calculates the affected percentage of areas which is
used to determine the overall impact by the MPC. This data was then applied to determine the potential
flash flood damage based on a 100 year flood event, which would be less than one foot in depth, with an
estimated damage of 10%. The overall value of buildings and contents for community assets identified in
the tables are estimated from appraised values supplied by the County Appraiser. The following table
represents the potential exposure loss for each community.

SUMMARY OF POTENTIAL HAZARD-RELATED EXPOSURE/LOSS IN SCHOOL
JURISDICTIONS
According to the FEMA FIRM (February 4, 1998) the towns of Louisville (Rock Creek), St. George
(Kansas River), Wamego (Kansas River), Onaga (Hise Creek), Blevue (Lost Creek, Kansas River), and
St. Marys (Kansas River, College Creek, Willard Creek) each have their own identified areas of
inundation.
The cities located along the Tuttle Creek (and Tuttle Creek Reservoir), the Big Blue River, and their
tributaries on the western county line, and the Kansas River and its tributaries on the southern county line
Page 158 of 252
have the highest risk of flooding in the county, although there were reported instances of occasional rural
flooding in the unincorporated areas as numerous other creeks and tributaries criss-cross the county.
City of St. George
A review of the FEMA Flood Insurance Rating Map noted two primary flood zones in the city of St.
George. One flood zone is a Zone A and lies in the northwest portion of the city, west of Jackson Street,
following Blackjack Creek to the Union Pacific (UP) railroad tracks where it becomes Zone AE. The
other flood area is designated as Zone AE and is located south of the UP railroad tracks in proximity to
Blackjack Creek and the Kansas River. It paaears that most of the designated flood areas are within
unpopulated areas and do not impact any major improved areas.
Additionally, an agricultural levee appears to be identified on the FEMA FIRM, and is located between
the Union Pacific Railroad tracks on the south side of St. George and the Kansas River, however the levee
does not appear to protect any existing assets.
City of St. Marys
A review of the FEMA Flood Insurance Rating Map (July 6, 1982) noted three flood zones in the city of
St. Marys. The flood zone farthest east is located along the east boundary of the corporate limits along
Willard Creek, and consists of Zones A3 and A8. The flood zone along the southwest corporate
boundaries of the city runs from Willard Creek to College Creek and is classified as Zone B. The
southeast flood zone follows College Creek, turning back west in the corporate limits, consists of Zones
A3, A6, and A0. Each of the flood zones appears to lie within developed areas of the city.
City of Wamego
A review of the FEMA Flood Hazard Boundary Map (March 17, 2003) noted three flood zones in the city
of Wamego. The flood zone along the Kansas River is classified as Zone AE and runs along the south
edge of the corporate limits of the city. Another flood zone is located along the east edges of Wamego and
follows Cat Creek (a tributary of the Kansas River), and is a combination of Zones A and AE. The third
zone follows East Unnamed Creek (a tributary of the Kansas River) from the west corporate limits of the
city, turning northwest back through the city, and out of the north corporate limits. This flood zone
consists of Zones A and AE. Most of these areas appear to contact developed and improved areas of the
city.
Belvue
Flood Hazard Boundary Maps (FHBM), and/or Flood Insurance Rate Maps (FIRM) were not available for
the city of Belvue, and FEMA has reported that there were no identified special flood hazard boundaries
identified in the city (NSFHA).
According to a review of the Kansas Department of Transportation (KDOT) County Road Map, Belvue
does not appear to have any major streams located within the city limits, but is located near the Kansas
River and Lost Creek.
Louisville
A review of the City of Louisville Flood Hazard Boundary Map (December 2, 1988) indicated Rock
Creek, a tributary of the Kansas River, flows through the city, and creates a flood zone that includes the
majority the cities developed areas, except for two small portions of Zone X, one along Highway 99 near
Plum Street, and another along the southern edge of the city limits. The primary flood zone that covers the
city is classified Zone AE.
Lousiville reported that the city does not have any critical facilities within its corporate limits and
therefore does not have vulnerability estimates for this asset classification.
Page 159 of 252
Onaga
A review of the FEMA Flood Insurance Rating Map (dated August 13, 1976) noted one primary flood
zone in the city of Onaga. The flood zone is designated Zone A, and follows Hine Creek across the
southern portion of the city, which has little development, except for one finger that extends north for
several hundred feet through a small portion of a developed area.
Page 160 of 252
Tornado
Situated in the north-east portion of Kansas, Pottawatomie County is located in a region that is prone to
the effects of sudden collision of cold/warm fronts creating thunderstorm high winds and tornadoes, and
for the most part, face an equal probability of risk for this hazard. This is due to the nature of the natural
weather events that occur in the county. Thunderstorm high winds and tornadoes are unpredictable and
random in nature. Since the majority of the county is rural, it does not present areas that are significantly
more vulnerable to property loss than others. The majority of people who live and work in Pottawatomie
County reside in the cities of Wamego, Saint Marys, Onaga, and Westmoreland, but the probability that a
jurisdiction would be affected more often than other areas in the county is considered statistically very
low.
The damage from a tornado is a result of high wind velocity and wind-blown debris. The potential damage
resulting from a tornado is directly correlated to the strength of the particular tornado and is qualified
utilizing the Enhanced Fujita (EF) Scale. The EF Scale assigns numerical values based on wind speeds
and categorizes tornadoes from EF0 through EF5.
The entire county is equally susceptible to damage from tornadoes. Although urbanized areas face the
greatest vulnerability because of their concentration of buildings, population, and lifeline utilities, the
economic impact from loss of crops, livestock, and storage facilities in the rural parts of the county can
have permanent or long-lasting impact on the communities in Pottawatomie County.
Pottawatomie County has a significant risk of tornadoes due to the number of thunderstorms the county
experiences each year. The likelihood of future events is estimated to remain the same as currently
calculated. Pottawatomie County can expect a tornado once every 2.3 years (0.46 chance/year), with
average annual damages of $41,984.
Although we extract data and probability of occurrence from historical information, the risk of a tornado
appears to be a random event. Additionally, the range of damage is largely dependent upon numerous
storm factors. The jurisdictions utilized qualitative data to estimate the probable percent damage based on
the overall average severity magnitude rating for Tornado identified in this plan. In many cases, due to the
small nature of the towns in Pottawatomie County, a tornado could virtually wipe out the entire
community (90% to 100% damage).

Dam / Levee
DAMS
There are 79,500 dams in the United States, according to the 2005 update to the National Inventory of
Dams. Approximately one third of these pose a "high" or "significant" hazard to life and property if
failure occurs.
A dam is a barrier across flowing water that obstructs, directs or slows down the flow, often creating a
reservoir, lake or impoundments. Most dams have a section called a spillway or weir over which, or
through which, water flows, either intermittently or continuously, and many have hydroelectric power
generation systems installed.
Dams are considered "installations containing dangerous forces" under International Humanitarian Law
due to the massive impact of a possible destruction on the civilian population and the environment. Dam
failures are comparatively rare, but can cause immense damage and loss of life when they arise.
National statistics show that overtopping due to inadequate spillway design, debris blockage of spillways,
or settlement of the dam crest account for 34% of all dam failures. Foundation defects, including
settlement and slope instability, account for 30% of all failures. Piping and seepage cause 20% of national
dam failures. This includes internal erosion caused by seepage, seepage and erosion along hydraulic
structures, leakage through animal burrows, and cracks in the dam. The remaining 16% of failures are
caused by other means. Dam failure can occur with little warning. Intense storms may produce a flood in a
few hours or even minutes for upstream locations. Flash floods occur within six hours of the beginning of
heavy rainfall, and dam failure may occur within hours of the first signs of breaching. Other failures can
take much longer to occur, from days to weeks, as a result of debris jams or the accumulation of melting
snow.
In Kansas, Federal Reservoirs are inspected, maintained and managed by either the U.S. Corps of
engineers or the Bureau of Reclamation. Emergency Action Plans (EAPs), including inundation maps, are
designated as For Official Use Only (FOUO), and are available only to local governments downstream for
use in an emergency. The Local Emergency Operations Plan (LEOP) should include inundation maps in
the event of a flooding event, or an emergency at the facility.
Dam inundation hazards are addressed separately by geographical area where data is available to the
county.
HIGH HAZARD DAMS
There were five (5) high hazard dams reported within Pottawatomie County, all of which were reported to
be located in the unincorporated areas of the county, with the exception of the College Creek Retention
Dam that is located in the corporate limits of St. Marys. The High Hazard Dams identified in
Pottawatomie County are detailed in the hazard profiles.
FEDERAL RESERVIORS WITHIN AND OUTSIDE POTTAWATOMIE COUNTY
The Tuttle Creek Reservoir serves as a border between Riley County and Pottawatomie County. Operated
by the U.S. Army Corps of Engineers, the dam is located 5-miles north of Manhattan (in Riley County).
Tuttle Lake provides flood protection along the Big Blue River downstream from the dam, as part of the
Kansas-Lower Republican River basin system of lakes. A potential breach or overtopping of the dam
could cause significant flooding in Manhattan, and other low-lying areas of the Big Blue, Little Blue, and
Black Vermillion Rivers, and Fancy Creek, and affect populations as far away as Kansas City, Missouri.
There are two federal reservoirs located outside of Pottawatomie County that could have a negative
impact on the county in the event of a breach, overtopping, or failure of the dam. The worst-case scenario
of a dam failure from Milford (Lake) Dam (Republican River) or the Lovewell (Reservoir) Dam (White
Page 165 of 252
Rock Creek) appears to impact the bodies of water downstream and developed areas around them, but
assessment was not available as the Emergency Action Plans and inundations maps for these facilities are
classified under the Federal Patriot Act and were not available for evaluation and inclusion in public
documents. The Emergency Coordinator should have access to these dam's plans in the event of an
emergency. Reference the Dam/Levee Hazard profile for detailed descriptions for dams.
LEVEES
A levee is a man-made structure; usually earthen embankments designed and constructed in accordance
with sound engineering practices to contain, control, or divert the flow of water so as to provide protection
from temporary flooding. A levee is generally built parallel to a body of water (most often a river) in order
to protect lives and property behind it from some level of flooding.
FEMA is responsible for identifying flood risks in areas behind levees through flood analysis and flood
hazard mapping projects, including updating the nation’s hazard maps through an effort called Flood Map
Modernization (Map Mod). In addition, FEMA also provides criteria to define which protect against the
1-percent-annual-chance flood. FEMA does not examine or analyze structures to determine their
performance in a given flood event. The levee owner must provide documentation to show that a levee
meets current design, operations, and maintenance criteria. FEMA will accredit levees based on a review
of these criteria. Levee owners or communities have a responsibility to provide documentation that a levee
meets the requirements of Title 44 of the Code of Federal Regulations, Section 65.10, as part of a
study/mapping project. Procedure Memorandum 34 (PM 34) allows for the issuance of a deadline to the
community for submitting the required documentation. (Source: FEMA)
FEMA – Region VII reported that their MAP Mod modernization program focuses on levees found on
existing FEMA Flood Maps (FIRMS) prior to update. FEMA is initiating a process to notify owners,
schedule meetings, and provide guidance to owners. The intent is to assist meeting Federal requirements
and accredit identified levees.
The State of Kansas has four statutes that regulate the design and construction of levees. The Statutes
include: 12-635 Flood Protection; Eminent Domain; 14-434 Power to Regulate; 19-3301 Flood Control;
Counties, and 24-816 Within 1st Class Cities. These statutes guide an owner or community through the
process of developing levees within the county, and mandate requirements for reporting and maintenance
of the levee(s).
Levee failure could be attributed to many factors including engineering failure, inadequate height, erosion,
soil quality, ineffective levee board system, seepage, and other types of hydrologic issues that could
disrupt the integrity of a levee. Developing a sound maintenance plan along with monitoring water flow
and construction conditions to certify levees are the best approach to preventing future failure. Ordinances
which monitor and control construction and construction excavations in the vicinity of a levee can also
prevent unforseen damage to systems.
Levee hazards are addressed separately by geographical area where data is available to the county. There
has been one levee identified in the City of St. George. Reference the Dam/Levee Hazard profile for a
detailed description.
The estimated vulnerability to dam exposure is provided in the table below, and is based on flood
inundation areas for Pottawatomie County (unincorporated), and planning jurisdictions determined by use
of FEMA boundary maps which were geo-coded using Manifold.Net, a GIS application. The GIS
application calculates the affected percentage of areas which is used to determine the overall impact by
the MPC. This data was then applied to determine the potential flood damage based on a 100 year flood
event, which would be less than one foot in depth, with an estimated damage of 10%. The overall value of
buildings and contents for community assets identified in the tables are estimated from appraised values
supplied by the County Appraiser. The following table represents the potential exposure loss for each

Page 167 of 252
Drought
Droughts can be grouped into four basic categories based on the severity and impact of the occurrence.
These are meteorological, hydrological, agricultural, and socioeconomic. Since they are largely
categorized by impact, it is possible, if not likely that these conditions could exist simultaneously.
Kansas's climate is characterized by cold winters and warm to hot summers. The eastern part of the state
generally receives moderate moisture in the winter and adequate moisture in the spring for the growing
season for crops.
The western portion of the state usually receives low to moderate moisture in the winter and marginal
moisture in the spring for the growing season for crops. The semi-arid conditions that prevail in the
western portion of the state also experiences average wind speeds of 12 to 17.5 mph which causes dry
conditions in a very short period of time.
This combination of hot summers and limited precipitation in a semi-arid geography places Kansas in a
potential position of suffering a drought in any given year. The climatic conditions are such that a small
departure in the normal precipitation during the hot peak growing period of July and August could
produce a partial or total crop failure. The fact Kansas's economy is closely tied to agriculture only
magnifies the potential loss which could be suffered during drought conditions.
There is no distinct geographic boundary to drought, and it can occur in every area of the county equally.
While Pottawatomie County buildings, critical facilities, infrastructure and lifelines may be exposed to
extreme weather related conditions brought on by a period of drought, it is expected that the greatest
exposure to this hazard is on the population, agriculture, and livestock of Pottawatomie County. Hazard
workshops are considered a viable option to educate the local residents and will be considered in the
future. See Section 5.2 Mitigation Actions.

Excessive Heat
During the summer months, the State of Kansas is frequently affected by severe heat hazards. Persistent
domes of high pressure establish themselves, which set up hot and dry conditions. This high pressure
prevents other weather features such as cool fronts or rain events from moving into the area and providing
necessary relief. Daily high temperatures range into the upper 90’s and low 100’s. When combined with
moderate to high relative humidity levels, the heat index moves into dangerous levels, and a heat index of
105 degrees is considered the level where many people begin to experience extreme discomfort or
physical distress.
There is no distinct geographic boundary to Excessive Heat. Excessive Heat can occur in every area of the
county equally. All populations, buildings, critical facilities, infrastructure and lifelines are considered
exposed to the excessive summer heat hazard and could potentially be impacted.
For purposes of this hazard mitigation plan, Pottawatomie County will assess this hazard's vulnerability
on a multijurisdictional planning basis instead of establishing separate geographic planning areas for this
type of event. The MPC noted that the greatest exposure to this hazard is on the population of
Pottawatomie County rather than impacting physical county assets. Hazard workshops are considered a
viable option to educate local residents on the dangers of summer heat.

Fog
Fog is a cloud at ground level, water droplets suspended in the air at the earth’s surface. Fog forms when
the air cannot hold all the moisture it contains. This happens when air is cooled to its dew point, which is
the temperature at which air is holding as much moisture as it can. When air reaches its dew point it
condenses into very small particles, forming the tiny water droplets that comprise fog.
The intensity and duration of fog varies with the location and type of fog - from early morning ground fog
that burns off easily to prolonged valley fog that can last for days. Generally, strong winds tend to prevent
fog formation.
Areas of Pottawatomie County along the river valleys and other low-lying areas can be at greater risk for
fog under certain meteorological conditions. However, no part of the county is free of the possibility of
experiencing fog. For purposes of this hazard mitigation plan, Pottawatomie County will assess this
hazard's vulnerability on a multijurisdictional planning basis instead of establishing separate geographic
planning areas for this type of event.
The MPC noted that the greatest exposure to this hazard is on the population of Pottawatomie County,
rather than property. However, fog does present some risk to motorized vehicle damage due to the limited
visibility created for motorists. Hazard workshops are considered a viable option to educate local residents
on the dangers of fog.

Hail
Hailstorms can cause extensive property damage affecting both urban and rural landscapes across large
areas. Fortunately, most hailstorms produce marble-size or smaller hailstones. These can cause damage to
crops, but they normally do not damage buildings or automobiles. Larger hailstones can destroy crops,
livestock, and wildlife and can cause extensive damage to buildings, including roofs, windows, and
outside walls. Vehicles can be total losses. When hail breaks windows, water damage from accompanying
rains can also be significant. A major hailstorm can easily cause damage running into the millions of
dollars.
Hail vulnerability is unpredictable and is a multijurisdictional hazard capable of producing extensive
damage from the impact of falling objects. Most thunderstorms do not produce hail, and ones that do
normally produce only small hailstones not more than one-half inch in diameter. However, hailstones can
grow larger than the size of a golf ball before falling to the ground. On September 3, 1970, a thunderstorm
in Coffeyville, Kansas produced a hailstone that measured more than 5 inches in diameter and 17 inches
around, weighing 1.7 pounds.
Hail is associated with severe thunderstorms. Powerful updrafts produce cumulonimbus clouds that tower
tens of thousands of feet above the ground. Air temperature in the upper levels of these clouds may be
-50°F or below. Hailstones grow as ice pellets, are lifted by updrafts, and collect supercooled water
droplets. As they grow, hailstones become heavier and begin to fall. Sometimes, they are caught by
successively stronger updrafts and are circulated through the cloud again and again, growing larger each
time the cycle is repeated. Eventually, the updrafts can no longer support the weight of the hailstones. As
hailstones fall to the ground, they produce a hailstreak that may be more than a mile wide and a few miles
long. A single thunderstorm can produce several hailstreaks (Changnon and Ivens, 1987).
Hailstorms occur every year in Kansas. Fortunately, most of these cause minimal damage. However,
storms producing large hail and causing extensive damage are ingrained in the memories of many Kansas
residents. While it is not possible to prevent damage, efforts to mitigate the potential effects of hail can
help property owners to minimize their losses.
Severe weather watches and warnings often provide ample time to prepare for a hailstorm. When there is
a threat of severe weather, property owners should move vehicles and other valuable moveable objects to
locations that provide shelter from falling hail. Farmers should move livestock and machinery to sheltered
locations. If a hailstorm is approaching, take shelter inside. Close drapes, blinds, and window shades
inside your house to reduce the likelihood of shattered glass being blown inside. Then, move to an interior
room on the lowest level and stay there during the storm.
The entire Pottawatomie County area is equally susceptible to damage from hail in association with severe
thunderstorms.
The best protection against financial loss from hail is to purchase insurance. Homeowners and auto
insurance should include coverage for hail damage. Farmers should invest in crop insurance to protect
against catastrophic loss.

Terrorism / AT / CD
Planning for this category of hazard is similar to natural hazards in that these types of hazards can occur
randomly, or as a result of a natural plant or animal disease, which could impact the entire county (and
beyond) before the disease or bio-agent is discovered. For this reason, this hazard category will be
assessed on a countywide planning basis instead of establishing a separate geographic planning area for
this type of event.
Although initial detection of this type of event is considered uncontrollable, it is highly possible an act of
terrorism (domestic or other) could occur at any time given the right circumstances. However, the
probability of future occurrence is reduced due to proactive preventative action on the part of Federal,
State and local authorities. This proactive approach to preparation and prevention will help reduce the
potential for losses to property and life as a result of terrorist or FAD outbreaks.
A review of this type of hazard revealed few sources for estimating risk associated with terrorism,
agri-terrorism, and civil disorder, and appears to have a low risk probability. The State of Kansas required
each county to develop a Foreign Animal Disease Plan (FAD) for agricultural exotic diseases, and is
included in the plan as a state-mandated planning hazard.
For planning purposes this hazard category is considered to be a multijurisdictional hazard and the entire
planning area is considered equally susceptible to Terrorism / Agri-terrorism / Civil Disorder. There is no
documented history of Terrorism/AT/CD events in Pottawatomie County, it is difficult to project
likelihood and extent of damage from an event. Although there is potential for damage to property, the
MPC considers death or injury to residents of the county to be the biggest concern from these hazards.
JURISDICTIONS
USD 320 - Wamego Public Schools
USD 320 feels it has a particularly vulnerable population (young children) and therefore has included
additional steps in planning for possible Terrorism/AT/CD events beyond the county-level actions.

TSTM Wind
A severe thunderstorm is a thunderstorm which produces tornadoes, hail 0.75 inches or more in diameter,
or winds of 50 knots (58 mph) or more. Structural wind damage or damaged crops may imply the
occurrence of a severe thunderstorm. A thunderstorm is approaching severe levels when it contains winds
of 35 to 49 knots (40 to 57 mph) or hail ½-inch or larger but less than ¾-inch in diameter. Although not
considered “severe," lightning and heavy rain can also accompany thunderstorms.
In the case of severe thunderstorms, hail, wind, and tornadoes, the location and frequency of previous
events are probably the best determiners of future events. NCDC recorded events provided the basis for
the natural hazards analysis for Pottawatomie County, and identified severity and likelihood to prioritize
the hazard.
The entire county is equally susceptible to damage from thunderstorm high wind (TSTM Wind), and for
this Plan, is addressed as part of the multi-hazard planning category.

Utility Failure
Failure of electrical utilities or other components of the power infrastructure in Pottawatomie County can
seriously impact public safety and health, vital government services, and the economy of the county.
Disruption of any of these functions could result from the majority of the natural, technological, and
manmade hazards described in this plan. Reliable data at the local level was not available, so
Pottawatomie County relied on vulnerability data provided in the State Mitigation Plan for analysis of this
potential hazard.
The electric power infrastructure in Kansas has been significantly affected by disasters and weather events
in the past, and is expected to continue into the future. Potential losses to the electric line infrastructure are
difficult to quantify. This information could potentially be obtained or estimated with assistance from
rural electric cooperatives in future updates to this plan.
For purposes of this hazard mitigation plan, Pottawatomie County will assess this hazard's vulnerability
on a multijurisdictional planning basis instead of establishing separate geographic planning areas for this
type of event. The MPC noted that the greatest exposure to this hazard is on the population of
Pottawatomie County rather that impacting physical county assets. Population impact is estimated at
19,220 residents.

Wildfire
Wildfire in the State of Kansas is better defined as rangeland fire. This type of fire generally originates as
a surface fire and can spread quickly across large areas. When wildfire does occur in Pottawatomie
County, it is also very rare that a home or business is lost, with most damage is limited to field crops.
Wildfire is most common in the spring when brush is still brown and dry, and when fields have reached
maturity in the fall months.
Current statistical analysis for Pottawatomie County indicates an average of 13.15 wildfire events a year,
and is classified as a high-risk hazard, but due to the rural setting of the county, and isolated locations of
wildfire, this hazard is addressed on a jurisdictional planning basis. Since the vast majority of reported
rangeland fires occur in unpopulated areas of the county, vulnerability appears to be limited to crops, with
a low impact to infrastructure and people.

Winter Storm
Winter storms can include blizzards, heavy snow, ice/sleet storms, extreme windchill and other cold
related hazards that can impact a community, county or region. The likelihood of future events is
estimated to remain the same as currently calculated. Pottawatomie County can expect approximately 4.2
winter storms a year, with average annual damages of $240,066.
Although we can extract data and probability of occurrence from historical information, the risk of winter
storm appears to be a random event.

4.5.4 Critical Facilities
An essential component of this Mitigation Plan is the inventory and identification of Pottawatomie
County’s critical facilities. The objective of the critical facilities inventory is to maintain information on
Page 182 of 252
buildings and support infrastructure that are vital to the response and recovery of a community from a
disaster. While it is important to reduce or eliminate risks to various sites throughout Pottawatomie
County, there are several types of structures that should be prioritized because damage to these critical
facilities can delay recovery, impact the delivery of vital services, cause greater damages to other sectors
of the county, or can put special populations at risk. For this reason, emphasis on planning and protection
of critical facilities is a priority for this mitigation plan.
There is no definitive list regarding what should be considered a “critical facility.” However, for purposes
of this Mitigation Plan, Pottawatomie County considers critical facilities to be those structures from which
essential services and functions for the continuation of public safety actions and disaster recovery are
performed or provided. These facilities include the supporting “life-line” infrastructure essential to the
mission of critical facilities.
A “best available” inventory of Pottawatomie County’s public and private assets, along with known
critical facilities, has been compiled using best available data. Sources used included the Division of
Property Valuation (Kansas Department of Revenue), HAZUS, and RS Means Estimated Construction
data. RS Means is the world's largest provider of construction cost and replacement cost data. Its data is
accepted and used by HAZUS and many other federal agencies. Since actual values associated with
specific structures could not be produced, aggregate costs (assessed value or RS Means data), by
class-type, were utilized along with the associated average unit cost. An objective was established to
implement collection of this type of data / information for the county as they begin to develop and refine
mitigation capability. It is anticipated that new information and data will continually be added to this plan
as technical capabilities are enhanced and implemented.
Page 183 of 252
Critical Facility Vulnerability
The following vulnerability assessment tables have been completed in order to best assess the current
vulnerability of Pottawatomie County based upon the current number and value of structures of critical
facilities.
Tables 4.5.4 (1) provides critical facilities ranked by required operational status during an emergency
event as follows (also reference the Table heading for description of levels 1 through 3):
Level 1 Facilities: Must not lose operational capability Level 2 Facilities: Must be operational within
24-hours following an event Level 3 Facilities: Must be operational within 72-hours following an
event

4.5.5 Development Trends and Implications
Land use patterns in Pottawatomie County have not changed much in past years. The 2005 Kansas Land
Cover Patterns map produced by the Kansas Applied Remote Sensing (KARS) program provides a fairly
accurate assessment of 11 land use/land cover classes. Land use patterns in Pottawatomie County have not
changed much in past years. The 2005 Kansas Land Cover Patterns map produced by the Kansas Applied
Remote Sensing (KARS) program provides a fairly accurate assessment of 11 land use/land cover classes.
The bulk of the land cover in the county (82.0%) is comprised of cropland and grassland. Urban
residential and urban industrial/commercial development comprises 1.4% of the land cover primarily in
Page 187 of 252
and around the towns of Wamego and St. Marys. Generally, built up areas continue to be located in or
around the major community in the county, with smaller concentrations located in rural areas along
Highway 24. Commercial land use is primarily limited to these same communities. Overall, commercial,
industrial, and residential development in Pottawatomie County has been largely regulated to manage and
enhance growth.
The State of Kansas has developed a unique method for utilizing water use data to determine not only
future water use, but also to project population in the state. Additionally, this method will be used to
verify the accuracy of the U.S.Census Bureau's sub-county population estimates for Kansas. This method
was developed by the Kansas Water Office and approved by the Kansas Water Authority.
In November 1998, the Kansas Water Office completed population and water demand projections for
every county, city, and rural water district in Kansas for the years 2000, 2010, 2020, 2030, and 2040.
These data will be utilized for growth projections for the county. Information regarding methodology and
projections can be found at: www.kwo.org/index.htm.
Pottawatomie County's population has varied greatly over the past 100 years, but overall, has experienced
an increase in population since 1900. Population growth and/or private development have increased from
18,470 in 1900 to 19,220 in 2006. The county is considered densely settled rural, and is located within a
region that, overall, ranks slightly below the state average for population growth, employment growth, and
business startup rate. (Kansas Department of Commerce, 2000)
Pottawatomie (UnInc.): Residential, Commercial, and Population Growth - Present and Future
Residential and commercial development is primarily concentrated around the largest incorporated cities,
Wamego and St. Marys, with the smaller rural communities of Belvue, Emmett, Havensville, Louisville,
Olsburg, Onaga, St. George, Westmoreland, and Wheaton having less development. Pottawatomie County
is projected to gradually increase in overall residential and commercial development by 1.28% annually,
as projected by the Kansas Water Office (KWO). Land use includes commercial, industrial, and
residential development in Pottawatomie County (unincorporated), and has been largely regulated by
zoning and construction codes.
While difficult to forecast, Pottawatomie County's future development trend through 2040 is assumed to
increase proportionate to the increase in population and will need to monitor and update mitigation
initiatives as the process unfolds. The property valuation rate, for the forseeable future, is also expected to
parallel the county population growth pattern of 1.28% annually for purposes of mitigation planning until
future data is available.
Belvue: Residential, Commercial, and Population Growth - Present and Future
Belvue's residential and commercial development is projected to experience a gradual increase in
population growth over the next 32 years of 1.50% annually (KWO). Projections are based on Kansas
Water Office data using Compound Annual Growth Rate as the means to develop projected growth
(KWO). Land use includes commercial, industrial, and residential development in Belvue, and has been
largely unregulated by zoning and construction codes.
While difficult to forecast, Belvue's future development trend through 2040 is assumed to increase
proportionate to the increase in population and will need to monitor and update mitigation initiatives as
the process unfolds. The property valuation rate, for the foreseeable future, is also expected to parallel the
city population growth pattern, and will remain at 1.50% annual growth for purposes of mitigation
planning until future data is available.

USD 320: Residential, Commercial, and Population Growth - Present and Future
USD 320 currently has four active schools located in Wamego. School enrollment is largely determined
by overall growth patterns of the city in which the schools reside. While difficult to forecast future
commercial and residential development, estimates of future community growth help predict school
funding decisions and facility expansion needs for the immediate future. Commercial and residential
growth projections are assumed to parallel the increase or decrease in local population projections, and
will need to monitor and update mitigation initiatives as the process unfolds. The property valuation rate,
for the foreseeable future, is also expected to parallel the city population growth patterns. It is likely that
the town of Wamego will continue to see population growth over the next 32 years of 1.37%, annually.
These figures are based on a compound annual growth rate (CAGR) developed from the Kansas Water
Office population projections through 2040.
USD 321 currently has three active schools located in the towns of St. Marys, Emmett, Delia (Jackson
County), and Rossville (Shawnee County). School enrollment is largely determined by overall growth

5.0 Mitigation Strategy
This section of the Plan outlines Pottawatomie County’s overall strategy and capabilities to reduce their
jurisdiction’s vulnerability to the effects of natural hazards, and include a discussion of Mitigation Actions
and Techniques. The Mitigation Actions are short-term, specific measures to be undertaken by
Pottawatomie County in order to achieve the identified objectives. Most of these actions are also
hazard-specific. Each action identifies the objective(s) it is intended to achieve, includes some general
background information to justify the proposed action, and provides measures to assure successful and
timely implementation.
It should be noted that individual risk assessment maps were completed for the unincorporated county,
and each of the six planning jurisdictions. Profile maps were provided to each jurisdiction to identify land
use information, critical facility information, infrastructure, and hazard areas. The local teams utilized
these maps to help identify their jurisdictional goals, objectives, and mitigation actions.
Mitigation Activities
In formulating this Mitigation Strategy, a wide range of activities were considered and discussed in order
to help achieve county goals and lessen the vulnerability of Pottawatomie County to the effects of natural
hazards. For each hazard ranked in the risk and vulnerability assessment as high or moderate (see Table
5.0 (1)), the Mitigation Planning Committee considered the six categories of mitigation techniques when
developing Actions for this plan. Those six categories are enumerated in Tables 5.0 (2) through 5.0 (7). A
list of all actions considered for this plan is provided in the Appendix.

Mitigation Techniques for Pottawatomie County
When considering the most appropriate mitigation techniques for Pottawatomie County to undertake, the
Mitigation Planning Committee reviewed the State Mitigation Plan and hazards list. More importantly,
Pottawatomie County contracted to have a specific all-hazard analysis performed in 2007 to identify
specific risk and vulnerability in the county. Hazard categories from the hazard analysis included natural,
chemical, vector, and civil/societal risks.
Following the review and discussion, a matrix was developed to target the plan’s priorities for proposed
mitigation actions. Consideration was given to potential county funding, technical capability, and overall
best approach to begin reducing exposure to hazards within the jurisdiction. Primary planning categories
used are presented in Table 5.0 (8).

5.1 MultiJurisdictional Goals and Objectives
Multihazard Requirement §201.6(c)(3)(i): [The hazard mitigation strategy shall include a] description of
mitigation goals to reduce or avoid long-term vulnerabilities to the identified hazards.
This section of the Plan outlines Pottawatomie County’s overall strategy to reduce their jurisdiction’s
vulnerability to the effects of natural hazards. The goals and objectives are provided in Table 5.2 (1).
Mitigation Goals - identifies the goal statements established by Pottawatomie County for this mitigation
plan. Each goal is meant to be general and broad in nature, and can only be achieved through the
long-term implementation of more specific objectives. It is intended that each goal listed below will be
more specifically addressed and realized through the implementation of short-term mitigation objectives
and actions.
Mitigation Objectives - The mitigation objectives are designed to support and correspond directly with the
jurisdiction goals to provide Pottawatomie County with some measurable, mid-range targets (2-5 years).
Each objective is numbered (i.e., “1.1”), with the first digit representing the corresponding jurisdictional
goal.
Page 197 of 252
TABLE 5.1 (1) POTTAWATOMIE COUNTY GOALS AND OBJECTIVES
TABLE 5.1 (1) POTTAWATOMIE COUNTY GOALS AND OBJECTIVES

Goal
3 Protect the jurisdiction's most vulnerable populations, buildings and critical facilities through the implementation of
cost-effective and technically feasible mitigation projects
Objectives
3.1
Maximize the use of available hazard mitigation grant programs to protect the jurisdiction’s most vulnerable populations and
structures.
3.2
Protect vital / critical facilities from the effects of natural hazards to the maximum extent possible.
Goal
4 Protect public health, safety and welfare by increasing the public awareness of existing hazards and by fostering both
individual and public responsibility in mitigating risks due to those hazards
Objectives
4.1
Increase the level of knowledge and awareness for the jurisdiction’s residents on the potential hazards that routinely threaten the
area.
4.2
Educate property owners on the affordable, individual mitigation and preparedness measures that can be taken before the next
hazard event.
4.3
Promote and educate the jurisdiction’s public and private sectors on potential agricultural terrorism and bio-terrorism.
4.4
Educate residents to the dangers of wildfire and the protection measures that may be taken such as buffer zones, etc., including
regulations regarding open burning and burn bans.
5.2 Mitigation Actions
Multihazard Requirement §201.6(c)(3)(ii): [The mitigation strategy shall include a] section that identifies and
analyzes a comprehensive range of specific mitigation actions and projects being considered to reduce the
effects of each hazard, with particular emphasis on new and existing buildings and infrastructure. Multihazard
Page 198 of 252
Requirement: §201.6(c)(3)(iii): [The mitigation strategy section shall include] an action plan describing how the
actions identified in section (c)(3)(ii) will be prioritized, implemented, and administered by the local jurisdiction.
Prioritization shall include a special emphasis on the extent to which benefits are maximized according to a
cost benefit review of the proposed projects and their associated costs.
The mitigation actions proposed for Pottawatomie County are listed on the pages that follow. Each has
been designed to achieve the goals and objectives identified through this multi-jurisdictional hazard
mitigation plan. Each proposed action includes the following:
(1) the appropriate category for the mitigation technique; (2) the hazard it is designed to mitigate; (3)
the objective(s) it is intended to help achieve; (4) some general background information; (5) the
priority level for its implementation (high, moderate or low); (6) potential funding sources, if
applicable; (7) the agency/person assigned responsibility for implementing each strategy; (8) a target
completion date.
Again, it is important to note that these mitigation actions are short-term, specific measures to be
undertaken by Pottawatomie County. It is expected this component of the plan will be the most dynamic;
it will be used as the primary indicator to measure the plan’s progress over time and will be routinely
updated and/or revised through future planning efforts.
Action Item Prioritization
The MPC qualitatively prioritized the four county goals based on protection of life and property, public
awareness, emergency services, implementation, and state-required planning directives (i.e., Foreign
Animal Disease, and Bio-terrorism plans).
The risk assessment served as the basis for prioritizing hazards in terms of county risk (Likelihood x
Severity = Risk). The prioritization represents current and future risk based on objective criteria.
The final step was to prioritize the action items as high, moderate or low based on a qualitative analysis
for actions deemed to be readily achievable. Emphasis was placed on education and public awareness as a
high priority, as knowledge helps reduces risk at the individual level. During annual review of the plan,
new and completed action items will be identified and appropriate changes made to the action plan.
Benefit - Cost Review
At the beginning of the planning process, each jurisdiction was asked to complete a questionnaire/survey
which covered six factors including, but not limited to:
•
•
•
•
•
•
Staff & Organizational Capability
Administrative and Technical Capability
Policy & Program Capability
Fiscal Capability
Legal Authority
Political Willpower
These topics are in essence the “STAPLEE” categories recommended by the FEMA Guidance on
Mitigation Planning. As a result of review, discussion, and the responses to the six factors listed above,
the MPC choose to use Method 2A, Simple Listing, (FEMA 386-5) as a qualitative method to generate a
benefit to cost review. The consultant reviewed the responses and, where needed, asked for clarification.
These responses were used to develop an overall strategy for the multi-jurisdictional plan. (The detail of
the responses can be reviewed at Section 3.10 and Section 4.5.5.)
A summary of the responses and the draft strategy was introduced at the first planning meeting. The
factors which universally impacted the rank of all actions were limited staff capability, limited fiscal
capability, and cautious political willpower. Subsequent to the first planning meeting, the jurisdictions
were asked to consider its responses to the questionnaire/survey and choose actions associated with the
Page 199 of 252
prioritized hazards. These choices were made in consideration of each jurisdictions responses to the
STAPLEE based answers. Once this initial prioritization was made, the jurisdictions were asked to rank
the actions by adding consideration of cost. In other words, in their opinion, which actions provided the
best benefit for the selected hazards and the associated cost.
Where budgetary or estimated costs for an action were available, that value is included. In many cases,
specific detail of potential actions or projects was not available. The use of estimated cost categories,
based on how funding is accomplished, was recommended as a starting point for evaluation. Those
categories are generally defined as follows:
No-cost/low-cost (less than $5,000);
Requires appropriation of funds (greater than $5,000 and less than $20,000); or
Requires significant funding (Greater than $20,000).
In general, no cost/low cost can be funded as part of operating expenditures; appropriation of funding
requires an action by the governing commission or council or prior budget requests; and significant
funding would require action by the governing body and potential commitment of outside funding
sources.
From a cost perspective, the jurisdictions chose to prioritize low-cost actions with specific benefit as high
ranking actions. A moderate ranking was given to actions which required appropriation of funding and
provided a specific benefit to an entire community, distinct population. All other actions were assigned a
lower priority. Actions were then given a final ranking by each jurisdiction to match the cost with overall
conditions, capability, and political climate. These rankings will be reviewed as part of the overall yearly
plan review process.

jurisdiction to join the program, and participation is voluntary. A benefit
of participation is that the citizens are provided the opportunity to
purchase flood insurance to protect themselves against flood losses.
Another consideration is that a jurisdiction that has been identified by
FEMA as being flood-prone and has not joined the NFIP within one year
of being notified of being mapped as flood-prone will be sanctioned.
Jurisdictions that regulate development in floodplains are able to
participate in the National Flood Insurance Program (NFIP). To
participate in the NFIP the jurisdiction must adopt and enforce floodplain
management regulations that meet or exceed the minimum requirements
of the program.

Benefit:
A significant amount of property damage during high wind events results
from tree failure. Trees that fall into utility lines have additional serious
consequences such as causing power outages, surges, fires and other
damage. The county’s ability to recognize and prevent hazardous tree
conditions (through inspection, pruning or removal) is the best defense
against problems and costly damages resulting from tree failure.
Specifically, trees located on county property which poses immediate
threats to property, utility lines and other critical facilities should be
addressed.

5.3 Implementation
Multihazard Requirement: §201.6(c)(3)(iii): [The mitigation strategy section shall include] an action plan
describing how the actions identified in section (c)(3)(ii) will be prioritized, implemented, and administered by
the local jurisdiction. Prioritization shall include a special emphasis on the extent to which benefits are
maximized according to a cost benefit review of the proposed projects and their associated costs.
The Pottawatomie County Multi-Jurisdictional Mitigation Plan will be implemented through the
delegation of assignments by the County Emergency Coordinator, and as specified within this Plan.
Mitigation Actions for each jurisdiction are listed and assigned specific implementation measures which
include the assignment of responsibilities to governmental departments and/or specific staff, along with
the establishment of a target completion date for each proposed mitigation action. When applicable,
potential funding sources were also listed.
It will be the responsibility of the Pottawatomie County Commission, and the designee(s) for each
jurisdiction, to confirm the target completion dates, assess progress, provide policy revisions, and give
final approval of the Plan and its objectives.
Planning and Incorporation of Mitigation Plan
The Pottawatomie County Emergency Management Department will support mitigation activities through
continued participation in the NFIP and flood plain development, in conjunction with the county
commission oversight of land planning, and other departments within the county, to guide and control
Page 245 of 252
development.
It is intended to utilize the Mitigation Plan as a reference guide for future growth and expansion efforts in
the county, and incorporate the goals, objectives and actions into other planning documents as revisions
and updates are made. Where feasible, mitigation actions will be incorporated into development and
planning ordinances to reduce potential risk to the county and residents.
It will be the responsibility of the Pottawatomie County Commission and incorporated city designees, to
confirm that these actions are ultimately carried out no later than the target completion dates unless
reasonable circumstances prevent their implementation (i.e., lack of funding availability). Otherwise, the
completion of each proposed mitigation action has been determined to be feasible within the timeframe
allowed.
Specific procedures for regular monitoring and reporting of progress on the proposed mitigation actions
are provided in Section 6.0 - Plan Maintenance.
Funding Sources
Although mitigation techniques will likely save money in the long run by avoiding losses, many projects
are costly to implement. Pottawatomie County will continue to seek outside funding assistance for
mitigation projects in both the pre- and post-disaster environment. This portion of the plan identifies the
primary federal and state grant programs for Pottawatomie County to consider, and also briefly discusses
local and non-governmental funding sources.
Federal
The following federal grant programs have been identified as funding sources which specifically target
hazard mitigation projects:
Pre-Disaster Mitigation Program Agency: Federal Emergency Management Agency
Through the Disaster Mitigation Act of 2000, Congress approved the creation of a national program to
provide a funding mechanism that is not dependent on a Presidential disaster declaration. The Pre-Disaster
Mitigation (PDM) Program provides funding to states and communities for cost-effective hazard
mitigation activities that complement a comprehensive mitigation program, and reduce injuries, loss of
life, and damage to and destruction of property.
The funding is based upon a 75 percent federal share, 25 percent non-federal share. The non-federal match
can be fully in-kind or cash, or a combination. Special accommodations will be made for “small and
impoverished communities”, who will be eligible for 90% federal share, 10% non-federal.
The Pre-Disaster Mitigation (PDM) Program was authorized by §203 of the Robert T. Stafford Disaster
Assistance and Emergency Relief Act (Stafford Act), 42 USC, as amended by §102 of the Disaster
Mitigation Act of 2000. Funding for the program is provided through the National Pre-Disaster Mitigation
Fund to assist States and local governments (to include Indian Tribal governments) in implementing
cost-effective hazard mitigation activities that complement a comprehensive mitigation program. All
applicants must be participating in the National Flood Insurance Program (NFIP) if they have been
identified through the NFIP as having a Special Flood Hazard Area (a Flood Hazard Boundary Map
(FHBM) or Flood Insurance Rate Map (FIRM) has been issued). In addition, the community must not be
suspended or on probation from the NFIP.
44 CFR Part 201, Hazard Mitigation Planning, establishes criteria for State and local hazard mitigation
planning authorized by §322 of the Stafford Act, as amended by §104 of the DMA. After November 1,
2003, local governments and Indian Tribal governments applying for PDM funds through the States will
have to have an approved local mitigation plan prior to the approval of local mitigation project grants.
States will also be required to have an approved Standard State mitigation plan in order to receive PDM
funds for State or local mitigation projects after November 1, 2004. Therefore, the development of State
Page 246 of 252
and local multi-hazard mitigation plans is key to maintaining eligibility for future PDM funding.
FEMA provides PDM grants to states that, in turn, can provide sub-grants to local governments for
accomplishing the following eligible mitigation activities:
•
•
•
•
•
•
State and local hazard mitigation planning,
Technical assistance [e.g. risk assessments, project development],
Mitigation Projects,
Acquisition or relocation of vulnerable properties,
Hazard retrofits,
Minor structural hazard control or protection projects, community outreach and education up to 10% of
State allocation
Flood Mitigation Assistance Program Agency: Federal Emergency Management Agency
FEMA's Flood Mitigation Assistance program (FMA) provides funding to assist states and communities
in implementing measures to reduce or eliminate the long-term risk of flood damage to buildings,
manufactured homes, and other structures insurable under the National Flood Insurance Program (NFIP).
FMA was created as part of the National Flood Insurance Reform Act of 1994 (42 U.S.C. 4101) with the
goal of reducing or eliminating claims under the NFIP.
There are three types of grants available under FMA: Planning, Project, and Technical Assistance Grants.
FMA Planning Grants are available to States and jurisdictions to prepare Flood Mitigation Plans.
NFIP-participating jurisdictions with approved Flood Mitigation Plans can apply for FMA Project Grants.
FMA Project Grants are available to States and NFIP participating jurisdictions to implement measures to
reduce flood losses. Ten percent of the Project Grant is made available to States as a Technical Assistance
Grant. These funds may be used by the State to help administer the program. Jurisdictions receiving FMA
Planning and Project Grants must be participating in the NFIP. Three examples of eligible FMA projects
include: the elevation, acquisition, and relocation of NFIP-insured structures.
FMA is a pre-disaster grant program, and is made available to states on an annual basis. This funding is
available for mitigation planning and implementation of mitigation measures only, and is based upon a 75
percent federal share, 25 percent non-federal share. States administer the FMA program and are
responsible for selecting projects for funding from the applications submitted by all jurisdictions within
the state. The state then forwards selected applications to FEMA for an eligibility determination. Although
individuals cannot apply directly for FMA funds, their local government may submit an application on
their behalf.
Hazard Mitigation Grant Program Agency: Federal Emergency Management Agency
The Hazard Mitigation Grant Program (HMGP) was created in November 1988 through Section 404 of
the Robert T. Stafford Disaster Relief and Emergency Assistance Act. The HMGP assists states and local
jurisdictions in implementing long-term mitigation measures following a Presidential disaster declaration.
To meet these objectives, FEMA can fund up to 75 percent of the eligible costs of each project. The state
or local cost-share match does not need to be cash, in-kind services or materials may also be used. With
the passage of the Hazard Mitigation and Relocation Assistance Act of 1993, federal funding under the
HMGP is now based on 15 percent of the federal funds being spent on the Public and Individual
Assistance programs (minus administrative expenses) for each disaster.
The HMGP can be used to fund projects to protect either public or private property, as long as the projects
in question fit within the state and local government's overall mitigation strategy for the disaster area, and
comply with program guidelines. Examples of projects that may be funded include: the acquisition or
relocation of structures from hazard-prone areas; the retrofitting of existing structures to protect them
from future damages; the development of state or local standards designed to protect buildings from future
Page 247 of 252
damages.
Eligibility for funding under the HMGP is limited to state and local governments, certain private nonprofit
organizations or institutions that serve a public function, Indian tribes and authorized tribal organizations.
These organizations must apply for HMGP project funding on behalf of their citizens. In turn, applicants
must work through their state, since the state is responsible for setting priorities for funding and
administering the program.
Public Assistance (Infrastructure) Program, Section 406 Agency: Federal Emergency Management
Agency
FEMA’s Public Assistance Program, through Section 406 of the Robert T. Stafford Disaster Relief and
Emergency Assistance Act, provides funding to local governments following a Presidential disaster
declaration for mitigation measures in conjunction with the repair of damaged public facilities and
infrastructure. The mitigation measures must be related to eligible disaster-related damages and must
directly reduce the potential of future, similar disaster damages to the eligible facility. These opportunities
usually present themselves during repair/replacement efforts.
Proposed projects must be approved by FEMA prior to funding. They will be evaluated for cost
effectiveness, technical feasibility, and compliance with statutory, regulatory and executive order
requirements. In addition, the evaluation must ensure that the mitigation measures do not negatively
impact a facility's operation or increase risk from another hazard.
The Public Assistance Program provides supplemental Federal disaster grant assistance for the repair,
replacement, or restoration of disaster-damaged, publicly owned facilities and the facilities of certain
Private Non-Profit (PNP) organizations. The Federal share of assistance is not less than 75% of the
eligible cost for emergency measures and permanent restoration. The State determines how the
non-Federal share (up to 25%) is split with the applicants.
Public facilities are operated by state and local governments, Indian tribes or authorized tribal
organizations and include:
•
•
•
•
•
Roads, bridges and culverts
Draining and irrigation channels
Schools, city halls and other buildings
Water, power and sanitary systems
Airports and parks
Private nonprofit organizations are groups that own or operate facilities that provide services otherwise
performed by a government agency and include, but are not limited to the following:
•
•
•
•
•
•
Universities and other schools
Hospitals and clinics
Volunteer fire and ambulance
Power cooperatives and other utilities
Custodial care and retirement facilities
Museums and community centers
SBA Disaster Assistance Program Agency: U.S. Small Business Administration
The SBA Disaster Assistance Program provides low-interest loans to businesses following a Presidential
Disaster Declaration (PDA). The loans target businesses that need to repair or replace uninsured disaster
damages to property they own, including real estate, machinery and equipment, inventory and supplies.
Businesses of any size are eligible, as well as non-profit organizations.
SBA loans can be utilized by their recipients to incorporate mitigation techniques into the repair and
Page 248 of 252
restoration of their business.
Community Development Block Grants Agency: U.S. Department of Housing and Urban Development
The Community Development Block Grant (CDBG) program provides grants to local governments for
community and economic development projects that primarily benefit low- and moderate-income people.
The CDBG program also provides grants for post-disaster hazard mitigation and recovery following a
PDA. Funds can be used for activities such as acquisition, rehabilitation or reconstruction of damaged
properties and facilities and for the redevelopment of disaster areas.
Individual and Households Program/Other Needs Assistance Agencies: FEMA and KDEM
The Individual & Households, Other Needs Assistance Program (ONA) provides financial assistance to
individuals or households who sustain damage or develop serious needs because of a natural or man-made
disaster. The funding share is 75% federal funds and 25% state funds. The ONA program provides grants
for necessary expenses and serious needs that cannot be provided for by insurance, another federal
program, or other source of assistance.
The current maximum allowable amount for any one disaster to individuals or families is $25,000. The
program gives funds for disaster-related necessary expenses and serious needs, including the following
categories:
•
•
•
•
•
•
•
Personal property
Transportation
Medical and dental
Funeral
Essential tools
Flood insurance
Moving and storage
In accordance with the Stafford Act, the program is initiated by inclusion in the Governor's request for a
presidential declaration.
The ONA Program is not intended to indemnify a victim against disaster losses or to purchase or replace
items or provide services that could be characterized as non-essential, luxury, recreational, or decorative.
The program provides individuals or households with assistance to recover from a disaster and establish a
habitable and sanitary living environment.
Kansas Emergency Management administers the ONA Program in cooperation with the federal
government.
Hazardous Materials Public Sector Training and Planning Grants Agency: U.S. Department of
Transportation-Title 49, Volume 2, Parts 100 to 185
This part sets forth procedures for reimbursable grants for public sector planning and training in support
of the emergency planning and training efforts of States, Indian tribes, and local jurisdictions to deal with
hazardous materials emergencies, particularly those involving transportation. These grants will enhance
the implementation of the Emergency Planning and Community Right-to-Know Act of 1986 (42 U.S.C.
11001).
The Hazardous Materials Emergency Preparedness (HMEP) grant program is intended to provide
financial and technical assistance as well as national direction and guidance to enhance State, Territorial,
Tribal, and local hazardous materials emergency planning and training. The HMEP Grant Program
distributes fees collected from shippers and carriers of hazardous materials to emergency responders for
hazmat training and to Local Emergency Planning Committees (LEPC’s) for hazmat planning.

State
A wide array of assistance programs are available to local jurisdictions through the state governmental
agencies to assist in the event of a disaster, including small business loans, recovery programs, and
mitigation programs, depending on needs and type of declared disaster in the jurisdiction. It is the intent
of Pottawatomie County to research and identify specific program funding that may be available for
specific goals and objectives identified in this plan.
Local
Local governments depend upon local property taxes as their primary source of revenue. These taxes are
typically used to finance services that must be available and delivered on a routine and regular basis to the
general public. If local budgets allow, these funds may be used for other purposes in the general public
interest. Many times these funds are used to match federal or state grant programs when required for
large-scale projects.
Non-Governmental
Another potential source of revenue for implementing local mitigation projects is monetary contributions
from non-governmental organizations, such as private sector companies, churches, charities, community
relief funds, the Red Cross, hospitals, land trusts and other non-profit organizations.

6.0 Plan Maintenance
6.1 Monitoring Schedule
Multihazard Requirement §201.6(c)(4)(i): [The plan maintenance process shall include a] section describing the
method and schedule of monitoring, evaluating, and updating the mitigation plan within a five-year cycle.
During each year, periodic monitoring and reporting on the progress of the plan is required to evaluate the
goals and objectives for each jurisdiction in this multijurisdictional plan. This will allow the overall plan
to stay current and will measure the effectiveness of the plan. The plan has therefore been designed to be
user-friendly in terms of monitoring implementation and preparing regular progress reports.
The plan is a public document, and will remain available at the Emergency Coordinator Operations
Office, and at appropriate locations within each jurisdiction, for review and comment during normal
business operations. Public comment will be documented and included in annual reporting to the county
commission.
6.2 Evaluating Method
Each jurisdiction is responsible for a formal review of the mitigation plan on an annual basis with
emphasis on its unique hazards, goals, and actions. Each jurisdiction is responsible to maintain a
designated contact for its part of the plan and inform the EM. This review will include the following as a
minimum scope:
• The EM, as Plan Administrator is responsible for scheduling an annual meeting of the Mitigation
Planning Committee, or other group that may be designated such as the Local Emergency Planning
Committee (LEPC), for the purpose of the overall formal review of the plan components.
• The EM will provide an annual report and/or presentation to the Board of County Commissioners
(BOCC) on the implementation status of the plan during a public forum meeting. This forum can either
be a scheduled county commissioners meeting or special meeting called to review mitigation planning.
This report will include, at a minimum, a completed, printed version of the Mitigation Action Plan
(MAP - provided as a link in the Appendix).
• The report will include an evaluation of the progress, effectiveness, and appropriateness of the
mitigation actions proposed in the plan. The report will recommend, as appropriate, any required
changes or amendments to the plan.
If the BOCC, on behalf of any or all of the jurisdictions, determines that the recommendations warrant
modification to the plan, the BOCC may initiate a plan amendment as described in the Revisions and
Updates Section.
The MAP lists the mitigation actions recommended in this plan. It has been designed to provide
Pottawatomie County with a user-friendly tool for monitoring the implementation of the mitigation
actions recommended in the plan, and for reporting progress to the BOCC or their appointed
representative. Mitigation actions may be sorted using the MAP according to the following:
1. By action number; 2. By category; 3. By hazard; 4. By priority; 5. By responsibility assigned to; 6.
By target completion date.
The spreadsheet file is provided as a link and will be maintained and updated along with the Pottawatomie
County Hazard Mitigation Plan.
6.3 Revisions and Updates - Schedule
Page 251 of 252
Periodic revisions and updates of the plan are required to ensure that the goals and objectives for
Pottawatomie County are kept current. More importantly, revisions may be necessary to ensure the plan is
in full compliance with federal regulations and state statutes. This portion of the plan outlines the
procedures for completing such revisions and updates.
Five-Year Plan Review
The hazard identification and assessment, jurisdiction vulnerability assessment, and mitigation capabilities
assessment should be reviewed, at a minimum, every 5-years to determine if there have been any
significant changes in Pottawatomie County that should be addressed and considered in the mitigation
plan. Increased development, increased exposure to certain hazards, the development of new mitigation
capabilities or techniques, and changes to federal or state legislation are examples of changes that may
affect the condition of the plan.
Further, following a disaster declaration, the plan will need to be reviewed and/or revised to incorporate
lessons learned and to address specific circumstances arising out of the disaster.
The results of any review, periodic or following a disaster, should be summarized in the plan update
report prepared for the mitigation plan under the direction of the EM. The annual report will include an
evaluation of the effectiveness and appropriateness of the plan, and will recommend, as appropriate, any
required changes or amendments to the plan.
If the BOCC determines that the recommendations warrant modification to the plan, the BOCC may either
initiate a plan amendment as described below or, if conditions justify, may direct the EM to undertake a
complete update of the plan.
Plan Amendments
An amendment to the plan should be initiated only by the BOCC, either at its own initiative or upon the
recommendation of the EM, or some other person or agency.
Upon initiation of an amendment to the plan, Pottawatomie County will forward information on the
proposed amendment to interested parties including, but not limited to, affected county departments,
residents and businesses. Information will also be forwarded to the Kansas Division of Emergency
Management. This information will be sent out in order to seek input on the proposed plan amendment for
not less than a forty-five (45) day review and comment period.
At the end of the comment period, the proposed amendment and review comments will be forwarded to
the EM (or designee) for consideration. If no comments are received from the reviewing parties within the
specified review period, such will be noted accordingly. The EM or designee will review the proposed
amendment along with the comments received from other parties, and submit a recommendation to the
county commissioners within sixty (60) days.
In determining whether to recommend approval or denial of a plan amendment request, the following
factors will be considered:
• There are errors or omissions made in the identification of issues or needs during the preparation of the
plan;
• New issues or needs have been identified which were not adequately addressed in the plan;
• There has been a change in information, data, or assumptions from those on which the plan was based.
Upon receiving the recommendation of the EM or designee, the BOCC will then proceed with its
established procedures for changing a document of this type. The BOCC will review the recommendation
(including the factors listed above) and any oral or written comments received at the public hearing.
Following that review, the BOCC will take one of the following actions:
Page 252 of 252
1. Adopt the proposed amendment as presented. 2. Adopt the proposed amendment with
modifications. 3. Refer the amendments request back to the EM for further consideration. 4. Defer
the amendment request for further consideration and/or hearing.
6.4 Incorporation into Existing Planning
Multihazard Requirement §201.6(c)(4)(ii): [The plan shall include a] process by which local governments
incorporate the requirements of the mitigation plan into other planning mechanisms such as comprehensive or
capital improvement plans, when appropriate.
The Pottawatomie County Emergency Management Department will continue to incorporate mitigation
planning activities into county planning functions by actively communicating the plan and its content to
other departments within the county. In conjunction with BOCC oversight and continued participation in
the NFIP, requirements of the mitigation plan can be incorporated into future comprehensive land
planning and zoning which will guide and control development. The intent will be to utilize the mitigation
plan as a reference guide for future growth and expansion efforts in the county, and to incorporate the
goals, objectives and actions of the plan into other planning documents as revisions and updates are made.
Where feasible, mitigation actions will be incorporated into development and planning ordinances to
reduce potential risk to the county and residents.
The jurisdictions participating in this multi-jurisdictional plan believe it has the capacity to stand alone
and will, for most situations, execute it as such. In the cases where the jurisdiction indicates a
comprehensive plan, or related planning function, this plan will be used or incorporated in to that process
as a reference or guiding document. As part of plan maintenance, the yearly review will examine and
document the integration of the mitigation plan with other plans and planning functions. This process will
also review new opportunities to incorporate and integrate the plan.
It will be the responsibility of the BOCC and participating jurisdictions to confirm that these actions are
ultimately carried out no later than the target completion dates unless reasonable circumstances prevent
their implementation (e.g., lack of funding availability). Otherwise, the completion of each proposed
mitigation action has been determined to be feasible within the timeframe allowed.
6.5 Continued Public Involvement
The plan is a public document, and will remain available at the Emergency Management Operations
Office for review and comment during normal business operations. Public comment will be documented
and included in annual reporting to the BOCC.
